Answer:

the answer is A it = 1

Explanation:

Let's solve your equation step-by-step.

14−5x−8−x=3+15−12x−6x

Step 1: Simplify both sides of the equation.

14−5x−8−x=3+15−12x−6x

14+−5x+−8+−x=3+15+−12x+−6x

(−5x+−x)+(14+−8)=(−12x+−6x)+(3+15)(Combine Like Terms)

−6x+6=−18x+18

−6x+6=−18x+18

Step 2: Add 18x to both sides.

−6x+6+18x=−18x+18+18x

12x+6=18

Step 3: Subtract 6 from both sides.

12x+6−6=18−6

12x=12

Step 4: Divide both sides by 12.

12x /12

x=1
