Answer:
x= -8
Explanation:
1) -3x+7x-8=34+9x-2
2) -3+7x-9x=8+34-2
3) -5x=40
4) x= 40/-5= -8
In the first step you have to separate the x from the numbers,placing on the left the terms that contain it and on the right the rest. When you do this step you need to change the signs of shifted numbers (-8 has become +8),then you can perform an algebraic sum (for istance: -3+(-9)=-12; -12+7=-5). Your last step will be the division between the term with and without x that are respectively denominator and numerator. After that, you'll conclude.
