[tex]- \frac{1}{2} x-7=-11[/tex]\

[tex]- \frac{1}{2} x=-11+7[/tex]          |adding 7 on both sides

[tex]- \frac{1}{2} x*2=-4*2[/tex]         |multiplying by -2 on both sides

[tex]-x = -8[/tex]                                |dividing by -1 on both sides

[tex]x = 8[/tex]

So, the solution is x =8

I'll offer you a deal in return for your 5 points:  I'll solve it . . . . You check it.

-1/2x - 7  = -11

Add  7  to each side:            -1/2 x  =  -4

Multiply each side by  2 :      - x  =  -8

Multiply each side by  -1 :      x  =  8

Take it Allalala !
