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

HOPE I HELPED!!! :)

You just have to add the variables and the numbers

So in easier way to simplify this is put the variables and the numbers by each other:

12x + 8x + 10 + 3

What is 12x + 8x?

20x

Then, add 10 + 3 = 13

Then, put it back into an equation.

20x + 13 is the answer!


Hope that helped!!
