6x+19+3x-6+5x-15=180

6x + 19 + 3x + - 6 + 5x + - 15 = 180

19 + - 6 + - 15 + 6x + 3x + 5x = 180

19 + - 6 = 13

13 + - 15 + 6x + 3x + 5x = 180

13 + - 15 = - 2

-2 + 6x + 3x + 5x = 180

6x + 3x = 9x

-2 + 9x + 5x = 180

9x + 5x = 14x

-2 + 14x = 180

-2 + 14x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 14x = 180 + 2

-2 + 2 = 0

0 + 14x = 180 + 2

14x = 180 + 2

180 + 2 = 182

14x = 182

Divide each side by '14'.

x = 13

x = 13

6x+19+3x-6+5x-15=180

14x = 180 - 19 + 6 + 15

14x = 182

x = 182 : 14

x = 13
