x-7=\frac{1}{2}x+\frac{1}{2}\left(-7\right)+16
Use the distributive property to multiply \frac{1}{2} by x-7.
x-7=\frac{1}{2}x+\frac{-7}{2}+16
Multiply \frac{1}{2} and -7 to get \frac{-7}{2}.
x-7=\frac{1}{2}x-\frac{7}{2}+16
Fraction \frac{-7}{2} can be rewritten as -\frac{7}{2} by extracting the negative sign.
x-7=\frac{1}{2}x-\frac{7}{2}+\frac{32}{2}
Convert 16 to fraction \frac{32}{2}.
x-7=\frac{1}{2}x+\frac{-7+32}{2}
Since -\frac{7}{2} and \frac{32}{2} have the same denominator, add them by adding their numerators.
x-7=\frac{1}{2}x+\frac{25}{2}
Add -7 and 32 to get 25.
x-7-\frac{1}{2}x=\frac{25}{2}
Subtract \frac{1}{2}x from both sides.
\frac{1}{2}x-7=\frac{25}{2}
Combine x and -\frac{1}{2}x to get \frac{1}{2}x.
\frac{1}{2}x=\frac{25}{2}+7
Add 7 to both sides.
\frac{1}{2}x=\frac{25}{2}+\frac{14}{2}
Convert 7 to fraction \frac{14}{2}.
\frac{1}{2}x=\frac{25+14}{2}
Since \frac{25}{2} and \frac{14}{2} have the same denominator, add them by adding their numerators.
\frac{1}{2}x=\frac{39}{2}
Add 25 and 14 to get 39.
x=\frac{39}{2}\times 2
Multiply both sides by 2, the reciprocal of \frac{1}{2}.
x=39
Cancel out 2 and 2.
