Question

Solve for x: 7x = 2x - 35. Option 1: 7 Option 2: 5 Option 3: -5 Option 4: -7

Answer 1

option 4

Explanation:

given

7x = 2x - 35 ( subtract 2x from both sides )

7x - 2x = 2x - 2x - 35 ( simplify both sides )

5x = - 35 ( divide both sides by 5 )

`(5)/(5)` x =
`(-35)/(5)` , that is

x = - 7
