3y

4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x

5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y

OK, so-3y + 15 - y = 39-3y + 15 - 15 - y = 39 - 15-3y -y = 24-4y = 24-y = 6y= -6.Hope this helps!

y = 8

3y

4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x

3xy + 3y2 = 3y (x + y)

(3y + 5)(y - 2)

x+7x+3y-y =8x+2y =2(4x+y)

it is equal to 6y plus y

It is y+3y-2y = 2y simplified

5x + 3y - 2 - x + y + 2 = 4x + 4y = 4(x + y)

X + 3y - 2y + 3y = X + (3-2+3)y = X + 4y

2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6

3y+5=y-25 2y=-30 y= -15
