Question

Solve. 7x = 2x – 35
a. 7
b. 5
c. –5
d. –7

Answer 1

7x = 2x - 35

First, subtract 2x from both sides. / Your problem should look like:
`7x - 2x = -35`
Second, subtract 7x - 2x to get 5x. / Your problem should look like:
`5x = -35`
Third, divide both sides by 5. / Your problem should look like:
`x = - (35)/(5)`
Fourth, simplify
`(35)/(5)` to 7. / Your problem should look like:
`x = -7`

Answer: x = -7 (D)

Answer 2

Step 1: Subtract 2x from both sides.7x−2x=2x−35−2x5x=−35 Step 2: Divide both sides by 5.‌5x5‌=‌−355‌x=−7 Answer: x = −7
