Which is the first step in simplifying 5(m - 2) = 3(m + 4) ?

• 5m - 2 = 3m + 4

• 5m - 10 = 3m + 12

• 5m + 10 = 3m + 12

• 5m - 10 = 3m - 12

Which is the second step in simplifying

 $\frac{1}{2}\ \left(\ 8m\ +\ 4\right)\ =\ 3m\ +\ 6\ ?$  

• 4m - 3m = 2 + 6

• 4m + 3m = -2 + 6

• 4m + 2 = 3m + 6

• 4m - 3m = -2 + 6

What is the first step in simplifying

 $\frac{1}{3}\left(\ 9x\ +\ 6\right)\ =\ \frac{1}{2}\left(\ 4x\ +\ 8\right)\ ?$  

• 3x - 2 = 2x + 6

• 3x + 2 = 2x + 4

• 3x + 3 = 2x + 6

• 3x + 2 = 2x - 4

What is the first step in solving the equation 2a - 4(a - 5) = 10
