1. Find the probability of selecting 2 red chips:
11/23 * 10/22 = 5/23
2. Find the probability of selecting 2 blue chips:
12/23 * 11/22 = 6/23

4/5 - 3/5 equals 1/5
x=7-2t
Move 7 to the other side. Sign changes from +7 to -7.
x-7=7-7-2t
x-7=-2t
Divide by -2 for both sides
x/-2-7/-2=-2t/-2
x/2+7/2=t
Answer: t= x/2+7/2 or t=7/2+x/2
