<u><em>Answer: B. m=-23 and -23=m. *The answer should be the negative sign.*</em></u>
Step-by-step 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!
