(x,0) lies on the graph of y=log(b)x, then x=​

2 x t divided by n

step-by-step explanation:

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

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.
