Describe and correct any error a student may have made when
solving the equation 0.15(y -0.2) = 2 - 0.5(1 - y).
0.15(y -0.2) = 2-0.5(1 - y)
0.15y - 0.3 = 2-0.5 + 0.5y
0.15y - 0.3 = 1.5 + 0.5y
100(0.15y -0.3) = 100(1.5 +0.5y)
15y - 30 = 150 + 50y
15y - 30 - 15y - 150 = 150 + 50y - 15y - 150
-180 = 35y
