Answer: the equation is 3x=12
Explanation:
The coefficient is 3 because the coefficient is the number being multiplied by the variable (x).
To find the solution you have to divide both sides of the equation by 3 to find what times 3 will give you 12. After dividing both sides by 3 you get this equation. X=4
So this means that the solution is 4.
