Answer:
X = 12
Explanation:
You'd begin by combining like terms. In this case, the like terms are 4x and 3x. 4x-3x = X or 1X because 4-3 is 1.
Therefore, X = 12.
Another way you could find X: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equations.
4*x-3*x-(12)=0
x-12 = 0
Then, add 12 to both sides of the equation.
x = 12
