Answer:
x=17
Hope it helps;)
Step-by-step explanation:
Subtract 8 from both sides of the equation
-x+8=9
-x+8-8=9-8
Simplify
Subtract the numbers
x= -17
Divide both sides of the equation by the same term
x= 17
-x/-1= -17/-1
Simplify
Cancel terms that are both in the numerator and denominator
Divide the numbers
x = 17
