9x-4y=23,2x-y=12

Solution

9 x - 4 y = 23, 2 x - y = 12

Solution

x = - 25, y = - 62

Solution steps

[9 x - 4 y = 23 2 x - y = 12]

Isolate

x

for

9 x - 4 y = 23 : x = \frac{23 + 4 y}{9}

Substitute

x = \frac{23 + 4 y}{9}

[2 \cdot \frac{23 + 4 y}{9} - y = 12]

Simplify

[\frac{46 - y}{9} = 12]

Isolate

y

for

\frac{46 - y}{9} = 12 : y = - 62

For

x = \frac{23 + 4 y}{9}

Substitute

y = - 62

x = \frac{23 + 4 ( - 62 )}{9}

\frac{23 + 4 ( - 62 )}{9} = - 25

x = - 25

The solutions to the system of equations are:

x = - 25, y = - 62
