Question

Solve m - 13 equals 8

Answer 1

Answer: $21$

Add 13 to both sides

$m-13+13=8+13\\m=21$

Answer 2

Answer:

m=21

Step-by-step explanation:

m-13=8

solve for m

we have to get m by itself

we have to move the 13 over to the eight

remember when you move something to the opposite side of the equal sign the sign changes.In this case the -13 will change to a positive 13

m=13+8

13+8

=21

m=21
