Question

Solve the equation 3(m + 5) = 3 + 3(2m + 2) for m.

Answer 1

`m=2`

Explanation:

`3\left(m+5\right)=3+3\left(2m+2\right)`

Expand:

`3m+3*5=3+3*2m+3*2`

`3m+15=3+6m+6`

`3m+15=6m+9`

Subtract 15 from both sides:

`3m+15-15=6m+9-15`

`3m=6m-6`

Subtract 6m from both sides:

`3m-6m=6m-6-6m`

`-3m=-6`

Divide both sides by -3:

`(-3m)/(-3)=(-6)/(-3)`

`m=2`

Answer 2

m=2
