Question

determine which equation below has a solution of x=2

a. 5x+8-12x=-6x+2x-3
b. 6x+4-12x=-10x+18x-3
c. -4x-6+x=-2x+x-10
d. -3x-8+x=-4x+x-10

Answer 1

Try simplifying and making x the subject for all the equations, i.e.:
5x+8-12x=-6x+2x-3
5x-12x+6x-2x = -3-8
* bringing all the x to one side *

Answer 2

You should first combine like terms to simplify the question. Then you bring all of the x to one side by either subtracting or adding it. Combine the rest if necessary. Solve for x.
