6\times \frac{1}{2}x+6-7=-3\left(-\frac{1}{2}x-1\right)
Use the distributive property to multiply 6 by \frac{1}{2}x+1.
\frac{6}{2}x+6-7=-3\left(-\frac{1}{2}x-1\right)
Multiply 6 and \frac{1}{2} to get \frac{6}{2}.
3x+6-7=-3\left(-\frac{1}{2}x-1\right)
Divide 6 by 2 to get 3.
3x-1=-3\left(-\frac{1}{2}x-1\right)
Subtract 7 from 6 to get -1.
3x-1=-3\left(-\frac{1}{2}\right)x+3
Use the distributive property to multiply -3 by -\frac{1}{2}x-1.
3x-1=\frac{-3\left(-1\right)}{2}x+3
Express -3\left(-\frac{1}{2}\right) as a single fraction.
3x-1=\frac{3}{2}x+3
Multiply -3 and -1 to get 3.
3x-1-\frac{3}{2}x=3
Subtract \frac{3}{2}x from both sides.
\frac{3}{2}x-1=3
Combine 3x and -\frac{3}{2}x to get \frac{3}{2}x.
\frac{3}{2}x=3+1
Add 1 to both sides.
\frac{3}{2}x=4
Add 3 and 1 to get 4.
x=4\times \frac{2}{3}
Multiply both sides by \frac{2}{3}, the reciprocal of \frac{3}{2}.
x=\frac{4\times 2}{3}
Express 4\times \frac{2}{3} as a single fraction.
x=\frac{8}{3}
Multiply 4 and 2 to get 8.
