Answer:

is That question or questions u should say correct

Answer 2

Answer:

1. Subtract

(a) 5x-3x = 2x

(b) 3a-4a = -a

(c) x²-13x² = -12x²

(d) 3y-(-y) = 3y+y = 4y

(e) -3a+7a = 4a

(f) 3abc - 3abc = 0

2. solve this same as Q1.

4. 0-(3x +2y -5xy)

= -3x-2y+5xy

5. (x²+x+1)+(x²-x+1)

= x²+x+1+x²-x+1

= 2x²+2

= 2(x²+1)

(-x²-x+1)-(2(x²+1))

= 2x²+2-x²-x+1

= x²-x+3
