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
Look at the arrow graph below; the more the dot is on the left means the more less number, the more the dot is on the right it means the more greater number. Sorry if my explanation is confusing.
