9x+4=3x+1=?

6x+4=1
6x=-3
x=-1/2

Check:
9(-1/2)+4=3(-1/2)+1
(18/2)*(-1/2)+4=(6/2)*(-1/2)+1
-4.5+4=-1.5+1
-.5=-.5

Simplifying
9x + 4 = 3x + 1

Reorder the terms:
4 + 9x = 3x + 1

Reorder the terms:
4 + 9x = 1 + 3x

Solving
4 + 9x = 1 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.
4 + 9x + -3x = 1 + 3x + -3x

Combine like terms: 9x + -3x = 6x
4 + 6x = 1 + 3x + -3x

Combine like terms: 3x + -3x = 0
4 + 6x = 1 + 0
4 + 6x = 1

Add '-4' to each side of the equation.
4 + -4 + 6x = 1 + -4

Combine like terms: 4 + -4 = 0
0 + 6x = 1 + -4
6x = 1 + -4

Combine like terms: 1 + -4 = -3
6x = -3

Divide each side by '6'.
x = -0.5

Simplifying
x = -0.5

9x+4=3x+1
6x=-3
Therefore x=-3/6 = -1/2

1- 9x + 4 = 3x + 1
2- 9x + 4 - 3x = 3x + 1 - 3x
3- 6x + 4 = 1
4- 6x + 4 - 4 = 1 - 4
5- 6x = -3
6- 6x / 6 = - 3 / 6
7- x = - 1/2
answer= x = 0.5

first you need to decide which side of the equals sign you gather the x's and which side the numbers, to give you a value for x.
You dont want a negative x, but its fine to have a negative number. so, take away 3x from both sides because thats the smallest amount hence is doesn't leave you with a negative x. so you are lefty with 6x+4=1. Now you must take the four away so that you are left with only an x on one side and a value on the other. so minus 4 from both sides to bring the left side down to 0. so now you have 6x=-3. So you have found what 6x is but you must find what x is equal to, so you divide both sides by 6 to get -0.5. so x=-0.5. And thats the answer.

Hope this helps. :)

First: combine "like" terms > subtract 4 from both sides (moving a variable to the opposite side means: use the opposite sign)....

9x + 4 - 4 = 3x + 1 - 4
9x = 3x - 3

Sec: subtract 3x from both sides....

9x - 3x = 3x - 3x - 3
6x = - 3

Third: solve for "x" by isolating it on one side > divide both sides by 6....

6x/x = - 3/6
x = -3/6

*Simplify the fraction into lowest terms, if possible....

x = -1/2

9x+4 = 3x + 1
9x +4 - 3x = 3x + 1 -3x
6x +4 =1
6x+4 -4=1-4
6x = -3
x = -3/6
x = -1/2
