Question

3m-5=7m-13 ?

Answer 1

Do you need to solve for m?

Answer 2

Yes

Answer 3

If so, we need to combine like terms.

3m - 5 = 7m - 13

Add 13 to both sides. -5 + 13 = 8

3m + 8 = 7m

Now subtract 3m from both sides of the equation, what do you get?

3m - 3m + 8 = 7m - 3m

8 = 7m - 3m

Answer 4

Whats 7m - 3m?

Answer 5

4m

Answer 6

Right, so our equation is now 8 = 4m.

Now divide both sides of the equation by 4.
\[\large \frac{ 8 }{ 4 } = \frac{ 4m }{ 4 }\]

Whats m =?
