Answer:

x = ⁻¹⁷⁄₆ or -2.83333333333

Step-by-step explanation:

3x · 4 = 7x - (x + 17)

Simplify both sides of the equation

3x (4) = 7x − (x + 17)

3x (4) = 7x + −1 (x + 17) (Distribute the Negative Sign)

3x (4) = 7x + −1x + (−1) (17)

3x (4) = 7x + −x + −17

12x = 7x + −x + −17

12x = (7x + −x) + (−17) (Combine Like Terms)

12x = 6x + −17

12x = 6x − 17

Subtract 6x from both sides

12x − 6x = 6x − 17 − 6x

6x = −17

Divide both sides by 6

6x / 6 = −17 / 6

Simplify

x = ⁻¹⁷⁄₆

Turn the fraction into a decimal

-17 ÷ 6 = -2.83333333333

  • x = ⁻¹⁷⁄₆ or -2.83333333333
