Answer:
X= 21
Step-by-step explanation:
First you want to add alike terms which will get you 8x+1=22+7x. Next you want to get your x on one side so I subtracted 7x which you get x+1=22. Last you want to get rid of your 1 to get x alone so you subtract 1 from both sides and you get x=21.
3x + 1 + 5x = 7 + 15 + 7x <em>combine like terms</em>
(3x + 5x) + 1 = (7 + 15) + 7x
8x + 1 = 22 + 7x <em>subtract 1 from both sides</em>
8x = 21 + 7x <em>subtract 7x from both sides</em>
x = 21
51+(4x+7)=90
4x+58=90
-58 -58
4x=32
4x/4=32/4
x=8
