38+7x-21=9
Use the distributive property to multiply 7 by x-3.
17+7x=9
Subtract 21 from 38 to get 17.
7x=9-17
Subtract 17 from both sides.
7x=-8
Subtract 17 from 9 to get -8.
x=\frac{-8}{7}
Divide both sides by 7.
x=-\frac{8}{7}
Fraction \frac{-8}{7} can be rewritten as -\frac{8}{7} by extracting the negative sign.
