Answer 2

Answer:

I hope it will help you, good luck

Step-by-step explanation:

1. 2x+(5x-3y)

= 2x + 5x - 3y

= 7x - 3y

2. 3x-(y- 2x)

= 3x - y + 2x

= 5x - y

3. 5a-( 3b -2a + 4c)

= 5a - 3b +2a - 4c

= 6a-3b -4c

4. -2 ( x2- y2 +xy ) -3 ( x2+y2-xy)

= -2x2+ 2y2- 2xy -3x2 -3 y2 +3xy

= -5 x2- y2+ xy

5. 3x +2y-{x-(2y-3)

= 3x + 2y- { x-2y -3}

= 3x+2y - x +2y+ 3

= 2x+ 4y +3

6. 5a - { 3a- (2-a) +4}

= 5a- { 3a- 2+ a +4}

= 5a- 3a - 2 + a +4

= 3a + 2

7. a-[ b- { a-( b-1) +3a}]

= a-[ b-{ a-b +1+ 3a}]

= a-[ b -4a +b -1]

= a-2b +4a +1

= 5a -2b +1

8. a-[ 2b -{3b -( 2b -3c)}]

= a- [ 2b - {3b-2b +3c}]

= a- [ 2b - b - 3c]

= a- b+3c
