7x-y=5,2x-3y=15

Solution

7 x - y = 5, 2 x - 3 y = 15

Solution

x = 0, y = - 5

Solution steps

[7 x - y = 5 2 x - 3 y = 15]

Isolate

x

for

7 x - y = 5 : x = \frac{5 + y}{7}

Substitute

x = \frac{5 + y}{7}

[2 \cdot \frac{5 + y}{7} - 3 y = 15]

Simplify

[\frac{10 - 19 y}{7} = 15]

Isolate

y

for

\frac{10 - 19 y}{7} = 15 : y = - 5

For

x = \frac{5 + y}{7}

Substitute

y = - 5

x = \frac{5 - 5}{7}

Simplify

x = 0

The solutions to the system of equations are:

x = 0, y = - 5
