4=1/2x + 6 .help please i dont get this!!?

Question

help please i dont get this!!

Answer 1

4=1/2x+6....

First you would want to subtract 6 from both sides to get:
4-6=1/2x+6-6
-2=1/2x

then you would divide both sides by 1/2 (or multiply by 2) to get the x alone:
-2*2=1/2x*2
x= -4

Answer 2

Multiply 2 on both sides to get rid of the fractions:
2(4)=2(1/2x+6)
8=x+12

Subtract 12 from both sides:
x=-4

Check:
4=1/2(-4)+6
4=-2+6
4=4

Answer 3

4 = 1/2x + 6
-2 = 1/2 x
-4 = x

Answer 4

4= 1/2x +6
first thing you do is substaract the 6 from both sides.
4= 1/2x +6
-6 -6

-2= 1/2x
then dividie the 1/2 from both sides
and your answer should be -4.

Answer 5

4 = 1/2x + 6
4 - 6 = 1/2 x
-2 = 1/2 x
2(-2) = 1/2x (2)
-4 = x

Answer 6

Just remember to treat both sides of the equation (the = sign) the same. So subtract 6 from both sides. That leaves you -2=1/2x. Then multiply both sides by 2. That leaves it all both finished.

Answer 7

x= -4

Answer 8

subtract 6 from both sides...
-2=1/2x
then divide by 1/2 (or multiply by 2)...
-4=x

Answer 9

4-6=1/2x
2=1/2x multiply both sides by 2
4=x

Answer 10

To The Name Jin: I'm somewhat stressed via your procedure.... If you are fixing for x: one million) 7/x +one million/two = four Transfer the (one million/two) to the opposite aspect of the same signal (7/x) = four - (one million/two) Combing the (four) and the (one million/two) (7/x) = (eight - one million) / two Simplify the correct aspect (7/x) = (7/two) Cross multiply 7x = 14 Divide all sides via (7) x = two Check: Replace x with "two" within the fashioned equation (7/two) + (one million/two) = four (eight/two) = four four = four four)one million/2x + x/three = 7 *whether it is one million/(2x) Combine the left sided phrases (three + 2x^two)/ (6x) = 7 Cross multiply 42x = 2x^two + three Transfer "42x" to the correct aspect zero = 2x^two - 42x + three Use the quadratic components to remedy this obstacle 7) -four/(x+one million) = two/(x-one million) Cross multiply two(x + one million) = -four(x - one million) Simplify 2x + two = -4x + four Add "-4x" to all sides 2x + 4x + two = four Subtract two from all sides 2x + 4x = four - two Combine like phrases 6x = two Divide all sides via 6 x = one million/three eight) three/x + four = nine/x - two Put constants ("four" and "two") on one aspect and variables ("three/x" and "nine/x") at the different aspect four + two = (nine/x) - (three/x) four + two = (nine - three)/x Combine like phrases 6 = (6/x) Cross multiply 6x = 6 Divide all sides via 6 x = one million Check: Replace "x" with "one million" (three/one million) + four = (nine/one million) - two three + four = nine - two 7 = 7 If #eight is three/(x+four) = nine/(x-two) Then move multiply nine(x + four) = three(x - two) Simplify 9x + 36 = 3x - 6 Subtract 36 from all sides 9x + 36 - 36 = 3x - 6 - 36 The 2 36's at the left aspect cancel out 9x = 3x - 6 - 36 Combine the ".6" and "-36" at the correct hand aspect 9x = 3x - forty two Subtract "3x" from all sides 9x - 3x = 3x - 3x -forty two Cancel out the 3x's at the correct hand aspect 9x - 3x = -forty two Substract 9x via 3x 6x = -forty two Divide all sides via 6 x = -7 Check: Substitute "x" with "-7" three/(-7 + four) = nine/(-7 - two) three/(-three) = nine/(-nine) -one million = -one million
