2x+7y=17,5x+3y=-1

Solution

2 x + 7 y = 17, 5 x + 3 y = - 1

Solution

x = - 2, y = 3

Solution steps

[2 x + 7 y = 17 5 x + 3 y = - 1]

Isolate

x

for

2 x + 7 y = 17 : x = \frac{17 - 7 y}{2}

Substitute

x = \frac{17 - 7 y}{2}

[5 \cdot \frac{17 - 7 y}{2} + 3 y = - 1]

Simplify

[\frac{85 - 29 y}{2} = - 1]

Isolate

y

for

\frac{85 - 29 y}{2} = - 1 : y = 3

For

x = \frac{17 - 7 y}{2}

Substitute

y = 3

x = \frac{17 - 7 \cdot 3}{2}

\frac{17 - 7 \cdot 3}{2} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = 3
