Question

Solve -3(6x - 1) = 6x-9. Justify each step.​

Answer 1

x =
`(1)/(2)`

Explanation:

- 3(6x - 1) = 6x - 9 ( divide both sides by - 3 )

6x - 1 = - 2x + 3 ( add 2x to both sides )

8x - 1 = 3 ( add 1 to both sides )

8x = 4 ( divide both sides by 8 )

x =
`(4)/(8)` =
`(1)/(2)`

Answer 2

x=0.5

Explanation:

3(6x - 1) = 6x-9

^ distribute

-18x-3=6x-9
