Answer:
The answer is true
Step-by-step explanation:
1. Substitute -6 where you see M.
We do this is because M is equal to -6. So where we see another M, we automatically know that it is -6.
2. Rewrite the equation.
It should go from (-3m+2=20) to {-3 (-6)+2=20}
3. Solve it
-3 times -6 equals positive 18. In multiplication, a negative times a negative equals a positive. Then add the 2 and you get 20. So our answer is true.
Here's a visual walk through.
-3m+2= 20 m=-6
-3(-6)+2=20
-3(-6)= 18
18+2=20
