Answer 1

x = - 2
`(1)/(4)`

Explanation:

10(5x + 12) = 2(5x + 15) Distribute the 10 and the 2

10(5x) + 10(12) = 2(5x) + 2(15)

50x + 120 = 10x + 30 Subtract 10x from both sides

50x - 10x +120 = 10x - 10x + 30

40x + 120 = 30 Subtract 120 from both sides

40x + 120 - 120 = 30 - 120

40x = -90 Divide both sides by 40

`(40x)/(40)` =
`(-90)/(40)`

x =
`(-9)/(4)` or - 2
`(1)/(4)`
