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

Solution

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

Solution

x = 1, y = - 1

Solution steps

[2 x - y = 3 4 x - y = 5]

Isolate

x

for

2 x - y = 3 : x = \frac{3 + y}{2}

Substitute

x = \frac{3 + y}{2}

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

Simplify

[y + 6 = 5]

Isolate

y

for

y + 6 = 5 : y = - 1

For

x = \frac{3 + y}{2}

Substitute

y = - 1

x = \frac{3 - 1}{2}

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = - 1

Popular Examples

x+2y=10,3x+4y=22

x + 2 y = 10, 3 x + 4 y = 22

x + y = 6, x - y = 8

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

x-5=1,3x-y=(12y)/2

x - 5 = 1, 3 x - y = \frac{12 y}{2}

x - y = 9, 2 x - y = 13
