Multiply everything if not that than add
94
(85+89+92+x)/4 = 90
(266+x)/4 = 90
(Multiply by 4 on each side to get rid of it)
266+x=360
(subtract 266 from each side)
x = 94
I hope it can help you hehehe
AC = 32
2x + 6x + 8 = 32 (plug in into equation)
8x + 8 = 32 (simplify)
8x + 8 (- 8) = 32 (-8) (subtraction of equality,)
(what you do to one side, you do to the other)
8x/8 = 24/8 (division of equality)
x = 3 (answer)
hope this helps
