Question

E Solve for x 6(x - 1) = 9(x + 2) x = -8 x= 3 x = 8​

Answer 1

Explanation:

6x - 6 = 9x + 18

-3x - 6 = 18

-3x = 24

x = -8 is the solution

Answer 2

x = -8

Explanation:

`6(x - 1) = 9(x + 2)`

Expand :

`6(x - 1) = 6x - 6 \\ 9(x + 2) = 9x + 18`

`6x - 6 = 9x + 18`

Collect like terms and simplify

`6x - 9x = 18 + 6 \\ - 3x = 24`

Divide both sides of the equation by -3

`( - 3x)/( - 3) = (24)/( - 3) \\ x = - 8`
