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

+ 6 +  = 18

First, simplify  to  / Your problem should look like:  + 6 +  = 18
Second, simplify  to  / Your problem should look like:  + 6 +  = 18
Third, simplify  + 6 +  to  + 6 / Your problem should look like:  + 6 = 18
Fourth, regroup terms. / Your problem should look like: 6 -  = 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

x = -84
