Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
x+y=5
Are you sure the directions don't have "solve the equation as x=___ and y=___"
y=±√15
y = 31
(2x)ysquared
You can't simplify this any further. y=-x is the equation of a line.
9
y=4 x+y=5 so it wud be:::::: x+4=5 solve it from there by doing 1 step equation :)
You cannot solve one linear equation with two variables.
To solve for y, divide both sides of the equation by -0.8.
87 = 3yDivide each side of the equation by 3:29 = y
