Solve for x
x=-y+\sqrt{5}
x=-\left(y+\sqrt{5}\right)
View solution steps
Steps by Finding Square Root
( x + y ) ^ { 2 } = 5
Take the square root of both sides of the equation.
x+y=\sqrt{5} x+y=-\sqrt{5}
Subtract y from both sides of the equation.
x+y-y=\sqrt{5}-y x+y-y=-\sqrt{5}-y
Subtracting y from itself leaves 0.
x=\sqrt{5}-y x=-\sqrt{5}-y
Subtract y from \sqrt{5}.
x=-y+\sqrt{5}
Subtract y from -\sqrt{5}.
x=-y-\sqrt{5}
The equation is now solved.
x=-y+\sqrt{5} x=-y-\sqrt{5}
Solve for y
y=-x+\sqrt{5}
y=-\left(x+\sqrt{5}\right)
