Question

0.8(5x+15)=2.6-(x+3)

Answer 1

0.8(5x + 15) = 2.6 - x + 3   Use the Distributive Property
       4x + 12 = 2.6 - x + 3   Combine like terms (2.6 and 3)
       4x + 12 = 5.6 - x         Add x to both sides
       5x + 12 = 5.6              Subtract 12 from both sides
              5x = -6.4             Divide both sides by 5
                x = -1.28
