Question

Solve the equation
3(x + 1) = 9+ 2x

Answer 1

3x(x)=3x
3x1=3
3x+3=9+2x

Answer 2

`x=6`

Explanation:

So we have the equation:

`3(x+1)=9+2x`

Distribute the left side:

`3x+3=9+2x`

Subtract 2x from both sides. The right side cancels:

`(3x+3)-2x=(9+2x)-2x\\x+3=9`

Subtract 3 from both sides:

`(x+3)-3=(9)-3\\x=6`

So, x is 6.
