Question

Does anyone know the step by step for this 9(m +5) - 3(m - 2) = 8m + 31

Answer 1

Answer :

Given :

• 9(m + 5) - 3(m - 2) = 8m + 31

We have to find value of m$.$

➠ 9(m + 5) - 3(m - 2) = 8m + 31

➠ 9m + 45 - 3m + 6 = 8m + 31

➠ 9m - 3m + 45 + 6 = 8m + 31

➠ 6m + 51 = 8m + 31

➠ 51 - 31 = 8m - 6m

➠ 20 = 2m

➠ m = 20/2

➠ m = 10

Hope It Helps!

Answer 2

1. distribute the left side of the equation
9m+45-3m+6 (make sure to distribute the negative sign)=8m+31
2. put all the variable terms on one side and the constants on the other
-2m=-20
3. divide by -2
m=10
