y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
x + y = -4x - y = 2x - y = 2x + y - y = 2 + yx = 2 + yx + y = -42 + y + y = -42 + 2y = -42 - 2 + 2y = -4 - 22y = -62y/2 = -6/2y = -3x = 2 + yx = 2 - 3x = -1The solution of the system is (-1, -3)

24/yx there isn't an = sign
It is two terms of an algebraic expression.
Tell whether the ordered pair (5, -5) is a solution of the system
ZW is parallel to YX.
yx * yx = y2x.Using the law of exponents, we add the 2 exponents, getting you 2x rather than just 'x'.
yx-3 is not an equation, and it has no graph.
