Answer 1

a) $7a - 2a + 4b - 2b \\ 5a + 2b$

b) $5 {y}^{2} - 5x - 8 {y}^{2} + 6 \\ 5 {y}^{2} - 8 {y}^{2} - 5x + 6 \\ - 3 {y}^{2} - 5x + 6$

c) $9 {x}^{2} + 4x - 3 {x}^{2} + 3x \\ 9 {x}^{2} - 3 {x}^{2} + 4x + 3x \\ 6 {x}^{2} + 8x$

d) $x + 7 + x - 10 - 1 \\ x + x + 7 - 10 - 1 \\ 2x - 4$

e) ${x}^{3} - {x}^{2} + 7 {x}^{2} + 10 {x}^{3} .4 \\ {x}^{3} + 6 {x}^{2} + 40 {x}^{3} \\ 41 {x}^{3} + 6 {x}^{2}$

f) $2 {x}^{3} - 7 {x}^{2} + 4x - 2 + 8 - 3 {x}^{2} \\ 2 {x}^{3} - 10 {x}^{2} + 4x + 6$

g) $4 {a}^{2} b - 3 {b}^{2} - 6 {b}^{2} - 2 {a}^{2} b - 1 \\ 4 {a}^{2} b - 9 {b}^{2} - 2 {a}^{2} b - 1 \\ 2 {a}^{2} b - 9 {b}^{2} - 1$
