In this equation, our main goal is to combine our ‘like terms’ or terms that share the same variable or power. In this case, the ( ) of both equations holds one term that has an X and one that is a lone number. We are now subtracting our two sets of like terms from one another.
9x-3x = 6x and 10-7= 3
After this, we just combine our answers from largest variable/exponent to the smallest, in this case, our answer ends up being 6x+3
