Question

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

Answer 1

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

2x+4+4=6x+4-4x

2x+8=2x+4

8=4

As 8 is unequal to 4, the answer is C, no solution.

Answer 2

First you need to solve the equation by distributing -

2(x+2) + 4 = 6x - 4(-1+x)  =

2x + 4 + 4 = 6x + 4 - 4x =

Then combine like terms -

2x + 8 = 2x + 4

Then get the x's on one side and the numbers on the other -

4 = (2x -2x = 0)

Since 4 = 0 isn't a solution, then the answer is: C. There is no solution
