can you find what x equals
2007-10-23 10:42:36 · 11 answers · asked by Anonymous in Science & Mathematics ➔ Mathematics
7x - 2(x + 6) = -2, simply the equation
7x -2x - 12 = -2, expand
5x - 12 = -2, combine like terms
5x = 10, add 12 to the other side
x = 2, divide by five
x = 2, that wasn't so bad now? hope this helps

7x - 2(x + 6) = -2
first distribute the -2 the integers in the parenthesis
7x - 2x -12 = -2
combine like-terms
5x - 12= -2
add the 12 to the -2
5x= 10
divide the 5 by the 10
x= 2
TADA!!!!!!!

7x - 2(x+6)= -2
7x - 2x + 12 =-2
5x + 12 = -2
5x/5 +12 = -2/5
x+ 12 = -0.4
- 12 -12
x = -12.4

solve for x
expand the equation---7x-2x-12=-2
put all the x's on one side and all the other crap to the other side by subtracting adding dividing multiplying, which ever one is needed---7x-2x=-2+12
simplify the expression---5x=10
and now solve for x by adding subtracting multiplying or dividing, in this case dividing---x=2
and thats your answer.
