Understand the problem

Solve for x:

−9−x=3+2x -9-x=3+2x

Step-by-step solution

To solve the equation, we will move similar elements to one side.

On the right side, we place the elements with X, while in the left side we place the elements without X.

Remember that when we move sides, the plus and minus signs change accordingly, so we get:

−9−3=2x+x -9-3=2x+x

We calculate both sides:−12=3x -12=3x

Finally, divide both sides by 3:

−123=3x3 -\frac{12}{3}=\frac{3x}{3}

−4=x -4=x
