3x-7y=-13,-4x+y=-16

Solution

3 x - 7 y = - 13, - 4 x + y = - 16

Solution

x = 5, y = 4

Solution steps

[3 x - 7 y = - 13 - 4 x + y = - 16]

Isolate

x

for

3 x - 7 y = - 13 : x = \frac{- 13 + 7 y}{3}

Substitute

x = \frac{- 13 + 7 y}{3}

[- 4 \cdot \frac{- 13 + 7 y}{3} + y = - 16]

Simplify

[\frac{52 - 25 y}{3} = - 16]

Isolate

y

for

\frac{52 - 25 y}{3} = - 16 : y = 4

For

x = \frac{- 13 + 7 y}{3}

Substitute

y = 4

x = \frac{- 13 + 7 \cdot 4}{3}

\frac{- 13 + 7 \cdot 4}{3} = 5

x = 5

The solutions to the system of equations are:

x = 5, y = 4
