What is m for this equation −7+4m+10=15−2m
Ratling [72]

<u><em>Answer: m=2 and 2=m *The answer should be have positive sign.*</em></u>

Step-by-step explanation:

4m-7+10=15-2m ← Group like terms

add/subtract numbers

-7+10=3

4m+3=15-2m

subtract by 3 both sides of an equation.

4m+3-3=15-2m-3

simplify.

4m=-2m+12

add 2m both sides of an equation.

4m+2m=-2m+12+2m

simplify.

6m=12

divide by 6 both sides of an equation.

6m/6=12/6

simplify by equation.

12/6=2

6*2=12

2*6=12

12/2=6

m=2

Hope this helps!

Thanks!

Have a great day!
