7x = 2x - 35
First, subtract 2x from both sides. / Your problem should look like: [tex]7x - 2x = -35[/tex]
Second, subtract 7x - 2x to get 5x. / Your problem should look like: [tex]5x = -35[/tex]
Third, divide both sides by 5. / Your problem should look like: [tex]x = - \frac{35}{5} [/tex]
Fourth, simplify [tex] \frac{35}{5} [/tex] to 7. / Your problem should look like: [tex]x = -7[/tex]
Answer: x = -7 (D)
