Answer:
y = -4.37
Explanation:
0.15(y - 0.2) = 2 - 0.5(1 - y)
distribute 0.15 into (y - 0.2) & distribute -0.5 to (1 - y)
0.15y - 0.03 = 2 - 0.5 + 0.5y
combine like terms on each side
0.15y - 0.03 = 1.5 + 0.5y
bring all y values to left side, all other numbers to right side
-0.35y = 1.53
solve for y, divide both sides by -0.35
y = -4.3714...
