12x + 10+3+8x? What do I have to do?

Simplifying

12x + 10 + 3 + 8x = 0

Reorder the terms:

10 + 3 + 12x + 8x = 0

Combine like terms: 10 + 3 = 13

13 + 12x + 8x = 0

Combine like terms: 12x + 8x = 20x

13 + 20x = 0

Solving

13 + 20x = 0

Solving for variable 'x'.

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

Add '-13' to each side of the equation.

13 + - 13 + 20x = 0 + - 13

Combine like terms: 13 + - 13 = 0

0 + 20x = 0 + - 13

20x = 0 + - 13

Combine like terms: 0 + - 13 = - 13

20x = - 13

Divide each side by '20'.

x = - 0.65

Simplifying

x = - 0.65
