Solve for x.
15 2-3x or 2x2-2

2

Step-by-step explanation:

If you are asking me to multiply 2*2 then subtract 2 you will get 2. Cause 2*2=4 then 4-2+2 so 2 is the answer if that is what you were asking.

On the firdt question i dont understand.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
