-8x+7y=-3,3x-7y=-12

Solution

- 8 x + 7 y = - 3, 3 x - 7 y = - 12

Solution

x = 3, y = 3

Solution steps

[- 8 x + 7 y = - 3 3 x - 7 y = - 12]

Isolate

x

for

- 8 x + 7 y = - 3 : x = - \frac{- 3 - 7 y}{8}

Substitute

x = - \frac{- 3 - 7 y}{8}

[3 (- \frac{- 3 - 7 y}{8}) - 7 y = - 12]

Simplify

[\frac{9 - 35 y}{8} = - 12]

Isolate

y

for

\frac{9 - 35 y}{8} = - 12 : y = 3

For

x = - \frac{- 3 - 7 y}{8}

Substitute

y = 3

x = - \frac{- 3 - 7 \cdot 3}{8}

- \frac{- 3 - 7 \cdot 3}{8} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 3
