Answer: A. -54. x=-54/-54=x. *The answer should be the negative sign.*
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
subtract by 4 both sides of an equation.
x+4-4=-50-4
simplify by equation.
-50-4=-54
50+4=54
x=-54/ and -54=x
