180=\frac{1}{3}x+\frac{1}{3}\times 30+x+30+x
Use the distributive property to multiply \frac{1}{3} by x+30.
180=\frac{1}{3}x+\frac{30}{3}+x+30+x
Multiply \frac{1}{3} and 30 to get \frac{30}{3}.
180=\frac{1}{3}x+10+x+30+x
Divide 30 by 3 to get 10.
180=\frac{4}{3}x+10+30+x
Combine \frac{1}{3}x and x to get \frac{4}{3}x.
180=\frac{4}{3}x+40+x
Add 10 and 30 to get 40.
180=\frac{7}{3}x+40
Combine \frac{4}{3}x and x to get \frac{7}{3}x.
\frac{7}{3}x+40=180
Swap sides so that all variable terms are on the left hand side.
\frac{7}{3}x=180-40
Subtract 40 from both sides.
\frac{7}{3}x=140
Subtract 40 from 180 to get 140.
x=140\times \frac{3}{7}
Multiply both sides by \frac{3}{7}, the reciprocal of \frac{7}{3}.
x=\frac{140\times 3}{7}
Express 140\times \frac{3}{7} as a single fraction.
x=\frac{420}{7}
Multiply 140 and 3 to get 420.
x=60
Divide 420 by 7 to get 60.
