Answer :

AL2006

                                            5x + 7 =  1/2 (10x + 12)

Eliminate the parentheses
on the right side:                  5x + 7 = 1/2(10x) + 1/2(12)

                                             5x + 7 =    5x       +      6

Subtract  5x  from each side:      7  =   6

There is no number for 'x' that can make  7 = 6 .
So there is no solution.

[tex]5x+7= \frac{10x+12}{2} =5x+6 \\ \\ 5x-5x=6-7 \\ \\ 0 = -1 \\ \\ 0 \neq x[/tex]

Question ; No solution  B)

Good Luck !
