5x-y=9,2x+4y=8

Solution

5 x - y = 9, 2 x + 4 y = 8

Solution

x = 2, y = 1

Solution steps

[5 x - y = 9 2 x + 4 y = 8]

Isolate

x

for

5 x - y = 9 : x = \frac{9 + y}{5}

Substitute

x = \frac{9 + y}{5}

[2 \cdot \frac{9 + y}{5} + 4 y = 8]

Simplify

[\frac{18 + 22 y}{5} = 8]

Isolate

y

for

\frac{18 + 22 y}{5} = 8 : y = 1

For

x = \frac{9 + y}{5}

Substitute

y = 1

x = \frac{9 + 1}{5}

\frac{9 + 1}{5} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 1
