Question 15 of 24

What is the solution to m + (–10) = –33?
A. m = –33
B. m = –23
C. m = 23
D. m = 33

Answer 1

Answer: B. m=-23 and -23=m. *The answer should be the negative sign.*

Explanation:

addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

add by 10 both sides of equation.

m-10+10=-33+10

simplify.

33-10=23

23+10=33

33-23=10

m=-23

It changes positive to negative.

Hope this helps!

Thanks!

Have a great day!
