y=5-x

Are you sure the directions don't have "solve the equation as x=___ and y=___"
solve for y so if x + y = 0 then y = -x
x + 1= -y implies x - y = 1
y=x+4
y=5-x
x=4 y=x+3 y=4+3 y=7
16
y=7+x =x=7-x

Are you sure the directions don't have "solve the equation as x=___ and y=___"
solve for y so if x + y = 0 then y = -x
If x equals the square root of ...., then you already have solved for x
x + 1= -y implies x - y = 1
x+y=5
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
