Question

3(7-9x)-5(5x+1)=-8(9x-4)

Answer 1

3(7 - 9x) - 5(5x + 1) = -8(9x - 4) Use the Distributive Property
21 - 27x - 25x - 5 = -72x + 32 Combine like terms (21 and -5 , -27x and -25x)
16 - 52x = -72x + 32 Add 72 to both sides
16 + 20x = 32 Subtract 16 from both sides
20x = 16 Divide both sides by 20
x =
`(16)/(20)` Simplify the fraction
x =
`(4)/(5)`
