All you have to do it combine one pair of like terms with eachother for each time you move further on the pyramid.

PYRAMID A : 

1ST LINE : -2x + 3

2ND LINE : -9x + 6 and 7x - 4

3RD LINE : 3x - 4 and -12x + 10 and 7x - 4

4TH LINE : 2x - 3 and x - 1 and -12x + 10 and 7x - 4

5TH LINE : -6x + 0 and 8x - 3 and x - 1 and -12x + 10 and 7x - 4.

6TH LINE : 2x - 6 and -8x + 6 and 8x - 3 and x - 1 and -12x + 10 and 7x - 4

7TH LINE : (we'll combine the first two terms from below) -1x - 2 and 3x - 4 and -8x + 6 and 8x - 3 and x - 1 and -12x + 10 and 7x - 4.
