Question

4 x +5y +7 +( -5x-y-3) + 3x-3y+2 ​

Answer 1

Step-by-step explanation:

4x+5y+7-5x-y-3+3x-3y+2

4x+3x-5x+5y-3y-y+7+2-3

7x-5x+5y-2y+9-3

2x+3y+6

Answer 2

$\mapsto \sf{}4 x +5y +7 +( -5x-y-3) + 3x-3y+2 \\ \mapsto \sf{}4x + 5y + 7 - 5x - y - 3 + 3x - 3y + 2 \\\mapsto \sf{} (4 - 5 + 3)x + (5 - 1 - 3)y + (7 - 3 + 2) \\ \mapsto \sf{} \: \: \: \: \: \: 2x + y + 6$
