1. 6p+14p-4q = 20p-4q
2. 5x-10y-6x-3y = -x-13y

1. 6p + 2 (7p - 2q) = 6p + 14p - 4q = 20p - 4q
2. 5 (x - 2y) - 3 ( 2x + y) = 5x - 10y -6x - 3y
3. -3 (x - 4y) 4 (5x - 3y) = (-3x + 12y) (20x - 12y) = -60x** + 36xy + 240xy -144y** = -60x** + 276 xy - 144y**
4. 4p + 3 - 2(p - 5) = 4p + 3 -2p +10 = 2p + 13
