Question

Solve for x : 4x-6=x+9

Answer 1

`x =5`

Explanation:

`4x - 6=x+9`

Subtract x from both sides

`4x -6-x=x+9-x`

`3x-6=9`

Add 6 to both sides

`3x-6+6=9+6`

`3x=15`

Divide both sides by 3

`(3x)/(3) = (15)/(3)`

`x = 5`

Answer 2

4x - 6 = x + 9

4x - x = 9 + 6

3x = 15

`x = (15)/(3) \\`

x = 5 ...
