-8+12x+7x+12=

19x+4

To solve the equation -8 + 12x + 7x + 12 = 0, follow these steps:

Step 1: Combine like terms on the left side of the equation:
-8 + 12x + 7x + 12 = 0
Combine the x terms: 12x + 7x = 19x
Combine the constants (numbers): -8 + 12 = 4
The equation becomes: 19x + 4 = 0

Step 2: Move the constant term to the right side of the equation:
Subtract 4 from both sides of the equation:
19x + 4 - 4 = 0 - 4
Simplifying, we get: 19x = -4

Step 3: Solve for x:
To isolate x, divide both sides of the equation by 19:
(19x) / 19 = (-4) / 19
Simplifying, we get: x = -4/19

So, the solution to the equation -8 + 12x + 7x + 12 = 0 is x = -4/19.
