4x-2y+3x+2y When simplified: 7x
Exactly (2y + 4) .
(2y + 1) + (y^2 + 1) = 2y + 1 + y^2 + 1 = y^2 + 2y + 2
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
2x+2y
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
Yes
It is equivalent to x + y + 4.
Just to clarify... the two expressions are equivalent for restricted y-values. What does that mean, and why are they equivalent?
4x-2y+3x+2y When simplified: 7x
-2x + 2y = 4 is equivalent to twice -2 + y = 2 which is the equation of a straight line.
