D = 2C
D - 15 = C + 22
Substitute 2C for D in the second equation and solve for C. Insert that value into the first equation to solve for D. Check by putting both values into the second equation.
D - 15 = C + 22

Initially:
Cam has X stickers.
Dan has 2x.
Dan gives Cam 15 stickers:
Cam has x + 15 stickers.
Dan has 2x - 15 stickers.
2x - 15 = (x + 15) + 22.
X = 52 stickers.
x + 15 = 52 + 15 = 67 stickers.
2x - 15 = 2*52 - 15 = 89 stickers.
