(7x-3y) + (2x+5y) = 9x+2y
-4(7x-3y-z)-(-6)(9x-z+2)
the simplest form of 5x + 3y +2x - 6y is 7x-3y
x+7x+3y-y =8x+2y =2(4x+y)
7x = -3y + 12
(7x-3y) + (2x+5y) = 9x+2y
-4(7x-3y-z)-(-6)(9x-z+2)
5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
the simplest form of 5x + 3y +2x - 6y is 7x-3y
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
x+7x+3y-y =8x+2y =2(4x+y)
7x = -3y + 12
the answer to this problem is -2x^2y^2
(3,3)
It is 16y+23x simplified
Answers to pick: -2x - y = 4 2x + y = -2 -8x + 4y = -16 -4x + 2y = -8 -x - 2y = 6 -7x + 4y = 16 2x + 3y = 6 3x + 2y = 4
