2y-x=-9,7y-2x=3

Solution

2 y - x = - 9, 7 y - 2 x = 3

Solution

x = 23, y = 7

Solution steps

[2 y - x = - 9 7 y - 2 x = 3]

Isolate

y

for

2 y - x = - 9 : y = \frac{- 9 + x}{2}

Substitute

y = \frac{- 9 + x}{2}

[7 \cdot \frac{- 9 + x}{2} - 2 x = 3]

Simplify

[\frac{- 63 + 3 x}{2} = 3]

Isolate

x

for

\frac{- 63 + 3 x}{2} = 3 : x = 23

For

y = \frac{- 9 + x}{2}

Substitute

x = 23

y = \frac{- 9 + 23}{2}

\frac{- 9 + 23}{2} = 7

y = 7

The solutions to the system of equations are:

x = 23, y = 7
