Question

Solve for x. Show steps.

7x - 17 = 4x + 1

-x + 5 = x - 11

5x + 8 = 7x + 2

​

Answer 1

see below

Explanation:

⇒ 7x - 17 = 4x + 1

combine like terms

7x - 4x = 1 + 17

3x = 18

x = 18/3

x = 6

⇒ -x + 5 = x - 11

combine like terms

- x - x = - 11 - 5

-2x = -16

x = 16 / 2

x = 8

⇒ 5x + 8 = 7x + 2

combine like terms

5x - 7x = 2 - 8

- 2x = - 6

x = 6 / 2

x = 3

Answer 2

Combine the same numbers and do the opposite of either subtraction or addition.

Then, multiply or divide with the coefficient.
