16.2x=172-x
Combine 15.2x and x to get 16.2x.
16.2x+x=172
Add x to both sides.
17.2x=172
Combine 16.2x and x to get 17.2x.
x=\frac{172}{17.2}
Divide both sides by 17.2.
x=\frac{1720}{172}
Expand \frac{172}{17.2} by multiplying both numerator and the denominator by 10.
x=10
Divide 1720 by 172 to get 10.
