-2x-7+3y+9+4x+2y=

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

-5x-8+4y-y-7x-9y=

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

0,5a-2a+9-0,5a=

Answer 1

-2x - 7 + 3y + 9 + 4x + 2y = 2x + 5y + 2
x - y - 3x + 2 - 2x - 7 + 5y = -4x + 4y  - 5

-5x - 8 + 4y - y - 7x - 9y = -12x - 6y - 8

4x + 5 + 7y - x - 4 + x - 3x = 7y + 1

0.5 a - 2a + 9 - 0.5 a = -2a + 9

Answer 2

-2x-7+3y+9+4x+2y=     2x+5y-1

x-y-3x+2-2x-7+5y=        -4x+4y-5

-5x-8+4y-y-7x-9y=         -12x-6y-8

4x+5+7y-x-4+x-3x=       -x+7y+1

0,5a-2a+9-0,5a=          -2a+9
