2 to x+1=x+2 to 3 or 2 to x+3= x+2 to x+5 (the proportions end up being the same in the end)

I keep getting to the part after you FOIL, and then I get stuck

**Henry**, Thursday, April 7, 2011 at 8:43pm1. 2/(X+1) = (X+2)/3.

Cross multiply:

(X+1)(X+2) = 6,

X^2+2X+X+2 = 6,

X^2+3X+2 = 6,

X^2+3X+2-6 = 0,

X^2+3X-4 = 0,

(X+4)(X-1) = 0,

X+4 = 0, X = -4.

X-1 = 0, X = 1.

Solution Set: (-4,0),(1,0).

2. 2/(X+3) = (X+2)/(X+5),

(X+3)(X+2) = 2(X+5),

X^2+2X+3X+6 = 2X+10,

X^2+2X+3X-2X = 10-6,

X^2+3X = 4,

X^2+3X-4 = 0.
