X= -4; f(x)= -15
X= 2; f(x)= 3
X=5; f(x)= 12
Isolate the x. Note the equal sign. What you do to one side, you do to the other. Subtract 45 from both sides
x + 45 (-45) = 11 (-45)
x = 11 - 45
x = -34
-34 is your answer
hope this helps
If you divide 55 by 11 you get 5. You then divide 30 by 5 too and you get x=6
