How do you solve #\frac { 5q ^ { 2} } { 6} - \frac { q ^ { 2} } { 3} = 72#? Algebra Linear Equations Two-Step Equations and Properties of Equality 1 Answer Alan N. Nov 19, 2016 #q=+-12# Explanation: #(5q^2)/6-q^2/3 = 72# Multiply through by 6: #5q^2 - 2q^2 = 72xx 6# #3q^2= 72xx6# #q^2 = 144# #q= sqrt144# #q= +-12# Answer link Related questions How do you solve two step equations?
