Question

What is the value of x?
-2/7x+6+1/7x=18
x=

Answer 1

`- (2)/(7) x` + 6 +
`(1)/(7) x` = 18

First, simplify
`(2)/(7) x` to
`(2x)/(7)` / Your problem should look like:
`-(2x)/(7)` + 6 +
`(1)/(7) x` = 18
Second, simplify
`(1)/(7) x` to
`(x)/(7)` / Your problem should look like:
`- (2x)/(7)` + 6 +
`(x)/(7)` = 18
Third, simplify
`- (2x)/(7)` + 6 +
`(x)/(7)` to
`- (x)/(7)` + 6 / Your problem should look like:
`-(x)/(7)` + 6 = 18
Fourth, regroup terms. / Your problem should look like: 6 -
`(x)/(7)` = 18
Fifth, multiply both sides by 7. / Your problem should look like: 42 - x = 126
Sixth, subtract 42 from both sides. / Your problem should look like: -x = 126 - 42
Seventh, simplify 126 - 42 to 84. / Your problem should look like: -x = 84
Eighth, multiply both sides by -1. / Your problem should look like: x = -84

Answer: x = -84
