Answer:

4 is your value for m.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Do the opposite of PEMDAS.

First, add 5 & m to both sides:

2m (+ m) - 5 (+ 5) = - m (+ m) + 7 (+ 5)

2m + m = 7 + 5

Simplify. Combine like terms:

3m = 12

Isolate the variable, m. Divide 3 from both sides:

(3m)/3 = (12)/3

m = 12/3

m = 4

m = 4 is your answer.

Kia purchased 3 pounds of grapes and spent $11.63 on other items. She spent a total of $20. She used the following steps to find
Maurinko [17]
3x + 11.63 = 20
3x + 11.63 - 11.63 = 20 - 11.63
3x = 8.37

by subtracting the 11.63 from both sides, this tells us how much the grapes cost....not per lb., but for the total of all the grapes.
