Answer

x = 3

Work Step by Step

0.06 - 0.01(x + 1) = -0.02(2 - x) Distribute: 0.06 - 0.01x - 0.01 = -0.04 + 0.02x Combine like terms: -0.01x + 0.05 = -0.04 + 0.02x Subtract 0.02x from both sides: -0.03x + 0.05 = -0.04 Subtract 0.05 from both sides: -0.03x = -0.09 Divide both sides by -0.03: x = 3
