Question 2 options:

5

-5

25

-25

Answer 1

Answer: B. -5 x=-5 *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.

add by 10 both sides of an equation.

x-10+10=-15+10

simplify by equation.

-15+10=-5

15-10=5

10+5=15

15-5=10

It changes to positive to negative.

x=-5

Hope this helps!
