Question

7x - 2 = 8 - x solve the equation and check it

Answer 1

Answer:

x=1.25

Step-by-step explanation:

7x - 2 = 8 - x

First, we must isolate "x". I will move the lonely x from the right side to the left side, and the "-2" from the left side, to the right side.

7x-2+x = 8

7x+x = 8+2

8x = 10

Now we have to divide the 8 from the x to isolate x

x =1 0/8

x = 1.25

To check, lets see if the left side = rights side

7(1.25) - 2 = 8 - (1.25)

8.75 - 2 = 6.75

6.75 = 6.75

It works!
