[tex]- \frac{2}{7} x[/tex] + 6 + [tex] \frac{1}{7} x[/tex] = 18
First, simplify [tex] \frac{2}{7} x[/tex] to [tex] \frac{2x}{7} [/tex] / Your problem should look like: [tex] -\frac{2x}{7} [/tex] + 6 + [tex] \frac{1}{7} x[/tex] = 18
Second, simplify [tex] \frac{1}{7} x[/tex] to [tex] \frac{x}{7} [/tex] / Your problem should look like: [tex]- \frac{2x}{7} [/tex] + 6 + [tex] \frac{x}{7} [/tex] = 18
Third, simplify [tex]- \frac{2x}{7} [/tex] + 6 + [tex] \frac{x}{7} [/tex] to [tex]- \frac{x}{7} [/tex] + 6 / Your problem should look like: [tex] -\frac{x}{7} [/tex] + 6 = 18
Fourth, regroup terms. / Your problem should look like: 6 - [tex] \frac{x}{7} [/tex] = 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
