Answer: x=-17 and -17=x. *The answer should be the negative sign.*
Explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
subtract by 5 both sides of an equation.
x+5-5=-12-5
simplify.
12+5=17
17-5=12
17-12=5
x=-17 and -17=x
Hope this helps!
