2x-y=5,x+y=4

Solution

2 x - y = 5, x + y = 4

Solution

x = 3, y = 1

Solution steps

[2 x - y = 5 x + y = 4]

Isolate

x

for

2 x - y = 5 : x = \frac{5 + y}{2}

Substitute

x = \frac{5 + y}{2}

[\frac{5 + y}{2} + y = 4]

Simplify

[\frac{5 + 3 y}{2} = 4]

Isolate

y

for

\frac{5 + 3 y}{2} = 4 : y = 1

For

x = \frac{5 + y}{2}

Substitute

y = 1

x = \frac{5 + 1}{2}

\frac{5 + 1}{2} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 1

Popular Examples

2x-2y= 3/2 ,3x+y= 5/4

2 x - 2 y = \frac{3}{2}, 3 x + y = \frac{5}{4}

2 x - y = 7, 3 x + y = 3

*(6)2x-3y=4,3y-x=4

\cdot (6) 2 x - 3 y = 4, 3 y - x = 4

3m-4n=6,2m-3n=5

3 m - 4 n = 6, 2 m - 3 n = 5

x + y = 1, x - y = 5
