Question

Solve
3(2x - 5) = 9(10 - x)

Answer 1

`x = 7`

Explanation:

First, we need to expand the brackets:

`3(2x-5)=9(10-x)` (equation given)

`6x-15=90-9x`

`15x -15 = 90` (add
`9x` on both sides)

`15x = 105` (add
`15` on both sides)

`x = 7` (divide by
`15` on both sides)

Hope this helps :)

Answer 2

x=7

Explanation:

3(2x - 5) = 9(10 - x)

6x-15=90-9x

6x+9x=90+15

15x=105

x=7
