Oh, dude, you're hitting me with some math, huh? Well, technically, the answer for 3x + 4y is just 3x + 4y. I mean, you're not really simplifying it or anything, so that's all there is to it. Math can be a trip, man.

3x + 4y + 10 + 12x + y + 1 First, combine like factors: 3x +12x + 4y + y +10 + 1 Add them (or subtract) as necessary: 15x + 5y + 11
It is: 3x+10y+5 simplified

3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
