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

Solution

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

Solution

x = 3, y = 2

Solution steps

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

Isolate

x

for

2 x - y = 4 : x = \frac{4 + y}{2}

Substitute

x = \frac{4 + y}{2}

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

Simplify

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

Isolate

y

for

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

For

x = \frac{4 + y}{2}

Substitute

y = 2

x = \frac{4 + 2}{2}

\frac{4 + 2}{2} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 2

3 x + y = 3, 4 x - 3 y = 17

3x+2y+z=1,5x+3y+4z=2,x+y-z=1

3 x + 2 y + z = 1, 5 x + 3 y + 4 z = 2, x + y - z = 1

5x+2y=-3,3x-4y=-7

5 x + 2 y = - 3, 3 x - 4 y = - 7

- x + y = 1, 5 x + y = 1

x + y = 7, x - y = 3
