Distribute 5 to all monomials inside the parenthesis

5(m + 4) = 5m + 20

5m + 20 = 2m + 20

Isolate the m, subtract 2m from both sides, and 20 from both sides

5m (-2m) + 20 (-20) = 2m (-2m) + 20 (-20)

5m - 2m = 20 - 20

Simplify

3m = 0

isolate the m, divide 3 from both sides

3m/3 = 0/3

m = 0/3

m = 0

hope this helps

We can solve this equation by using the distributive property to open up 5(m+4), and then getting m on one side and the constants on the other and then solving for m. Doing this gives us:

5m+20=2m+20 Now we get m on one side
3m=0 Divide each side by 3
m=0 The answer
