What is the value of y in the equation 4 (5y - 8 - 2) = 185 - 15?

In an equation the Left hand side must equal the right hand side 4 (5y-8-2) = 185-15 20y-32-8=170 20y=170+32+8 20y=210 Therefore y=10,5 When you substitute the 10,5 and solve it on the left and side it's equal to 170 which is the answer on the right hand side
