Solve and show your work for the equation 4m + 2(m + 1) = 9m + 5

solve and show your work for the equation 3(4x – 2) = 9 + 2x + 5

4m + 2(m + 1) = 9m + 5

What we need to do here is combine like terms, then apply the inverse operation, and finally, isolate the variable. 

Here's how it's done: 

4m + 2m + 2 = 9m + 5
4m and 2m are like terms, so add them together. 
4m + 2m = 6m 

6m + 2 = 9m + 5
-6m         -6m

2 = 3m + 5
-5          -5

3m = -3
3m/3 = -3/3
m = -1 should be your answer.


Next one: 3(4x – 2) = 9 + 2x + 5
12x - 6 = 9 + 2x + 5
 -2x              -2x

10x - 6 = 9 + 5
10x - 6 = 14
        +6   +6

10x = 20
x = 2 should be your answer.
