4y
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
The value of y in the equation -2x plus 4y -4, is 1 plus x/2.
4y+6+9=4y+15
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
0
4y+y=10 5y=10 y=2
It is the same as: 6x+4y
x2 -y2 +4y-4=(x+y)(x-y)+4y-4
3y - 7 + y + 27 = 6y + 20 - 4y Collect terms: 4y + 20 = 2y + 20 Subtract 20 4y = 2y The only way that can happen is if y = 0
11-4y=-5 -4y=-16 y=4
