4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
It simplifies to: 4y-16
-4y = 2-10 , therefore, -4y = -8. From here, divide -4 on both sides and you will get that y = 2.
This simplifies to 3x-6+4y.
4y + 7 < 3y + 9 4y - 3y < 9 - 7 y < 2
4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
It simplifies to: 4y-16
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
If x - 4y = 2 and x + 4y = 2 then the only solution is when y = 0 and thus x = 2.
-4y = 2-10 , therefore, -4y = -8. From here, divide -4 on both sides and you will get that y = 2.
This simplifies to 3x-6+4y.
4y + 7 < 3y + 9 4y - 3y < 9 - 7 y < 2
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
The value of y in the equation -2x plus 4y -4, is 1 plus x/2.
I don't know whether it's y^2-3y+2+3y-4y-5 or 2y-3y+2+3y-4y-5, so I'll do both.y^2-3y+2+3y-4y-5y^2+(-3y+3y-4y)+(2-5); group them togethery^2+(-4y)+(-3)y2-4y-3OR2y-3y+2+3y-4y-5(2y-3y+3y-4y)+(2-5); group them together(-2y)+(-3)-2y-3
