-2x-3y=7,-13x+20y=322

- 2 x - 3 y = 7, - 13 x + 20 y = 322

x = - 14, y = 7

Solution steps

[- 2 x - 3 y = 7 - 13 x + 20 y = 322]

Isolate

x

for

- 2 x - 3 y = 7 : x = - \frac{7 + 3 y}{2}

Substitute

x = - \frac{7 + 3 y}{2}

[- 13 (- \frac{7 + 3 y}{2}) + 20 y = 322]

Simplify

[\frac{91 + 79 y}{2} = 322]

Isolate

y

for

\frac{91 + 79 y}{2} = 322 : y = 7

For

x = - \frac{7 + 3 y}{2}

Substitute

y = 7

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

- \frac{7 + 3 \cdot 7}{2} = - 14

x = - 14

The solutions to the system of equations are:

x = - 14, y = 7

2 x + 3 y = 2, x - y = 8

x - y = 5, x + 2 y = - 1

x - y = - 2, 8 x - 3 y = 24

x + y = 7, 25 x + 18 y = 147

\frac{5}{y} - \frac{2}{x} = 1, \frac{\frac{3}{836}}{x} - \frac{24}{y} = 1
