1) Simplify by adding the alike terms
>6x + 3x = 13.69
> 9x = 13.69
2) Divide both sides by 9
> 9x = 13.69
> 9x/9 = 13.69/9
> x = 1.5
>6x + 3x = 13.69
> 9x = 13.69
2) Divide both sides by 9
> 9x = 13.69
> 9x/9 = 13.69/9
> x = 1.5

6x + 3x = 13.69
9x = 13.69
9x ÷ 9 = 13.69 ÷ 9
x = 13.69/9
x = (13.69/9) × (100/100)
x = 1369/900
9x = 13.69
9x ÷ 9 = 13.69 ÷ 9
x = 13.69/9
x = (13.69/9) × (100/100)
x = 1369/900
