5(x + 8) = 7(x − 2)

Question

5(x + 8) = 7(x − 2)

hero · Answer

5(x - 2 + 10) = 7(x - 2)
5(x - 2) + 50 = 7(x - 2)
50 = 7(x - 2) - 5(x - 2)
50 = 2(x - 2)
25 = x - 2
25 + 2 = x

x = ?

5(x + 8) = 7(x − 2) 
Distribute the 7 and 7 on their respective sides

5(x + 8) = 7(x − 2)
5x+40=7x-14

Subtract 5x on both sides

 5x+40=7x-14
-5x      -5x
--------------
40=2x-14 

Add the 14 on both sides
 
 40=2x-14 
+14     +14
-----------
54=2x

Divide by 2 on both sides.

54/2=2x/2

 ?=x

I leave the last step to you :)

5(x+8)=7(x-2)
first open up the bracket and this you'll get 5x+40=7x-14
    then collect the like terms together =40+14=7x-5x
                                                                 54=2x 
                                     dividing both side by 2: 27=x    this final answer
