2x+5-4y=-1
Consider the first equation. Subtract 4y from both sides.
2x-4y=-1-5
Subtract 5 from both sides.
2x-4y=-6
Subtract 5 from -1 to get -6.
2x+5y-2x=5
Consider the second equation. Subtract 2x from both sides.
5y=5
Combine 2x and -2x to get 0.
y=\frac{5}{5}
Divide both sides by 5.
y=1
Divide 5 by 5 to get 1.
2x-4=-6
Consider the first equation. Insert the known values of variables into the equation.
2x=-6+4
Add 4 to both sides.
2x=-2
Add -6 and 4 to get -2.
x=\frac{-2}{2}
Divide both sides by 2.
x=-1
Divide -2 by 2 to get -1.
x=-1 y=1
The system is now solved.
