4(3x+ 5- 3x)=x+19

4(5) = x+19

20 = x + 19

  x = 20 - 19

   x = 1

Hi!

Use the distribution property.

4 * 3x = 12x

4 * 5 = 20

4 * -3x = -12x

12x + 20 - 12x = x + 19

-----------------------------------

Combine like terms and Simplify

12x - 12x + 20 = x + 19

20 = x + 19

Subtract 19 from both sides

20 - 19 = x + 19 - 19

1 = x

-----------------------------------

The answer is x = 1

Hope this helps! :)
