Answer 1

y = 2x + 5
y = 3x

substitute, y = 3x in y = 2x + 5

solve for x,
use x value to find y

What do the "?" mean?
I see them in most of your posted problems.

In this case, the "?" in this problem are part of the answer, so it didn't matter to me what they are.

But in your other posts, when they are part of the problem, I don't know what they are for, so I can't help you.

Maybe it's just me.

post back if you need more help
