Answer:
m = 3
Step-by-step explanation:
First, distribute the 5 to the values inside the parentheses.
6 + 5m + 5 = 26
Combine like terms: 5m + 11 = 26
Then, you want to isolate the variable so you subtract 11 from both sides because what you do on one side must be done to the other.
5m + 11 - 11 = 5m
26 - 11 = 15
5m = 15
Then divide both sides by 5.
5m / 5 = m
15 / 5 = 3
m = 3
18r^2 - 24r + 42. When you want to express something as squared or with an exponent you put ^ this symbol then the number(s)
