-7x-2y=-1,3x-2y=11

- 7 x - 2 y = - 1, 3 x - 2 y = 11

x = \frac{6}{5}, y = - \frac{37}{10}

Solution steps

[- 7 x - 2 y = - 1 3 x - 2 y = 11]

Isolate

x

for

- 7 x - 2 y = - 1 : x = - \frac{- 1 + 2 y}{7}

Substitute

x = - \frac{- 1 + 2 y}{7}

[3 (- \frac{- 1 + 2 y}{7}) - 2 y = 11]

Simplify

[\frac{3 - 20 y}{7} = 11]

Isolate

y

for

\frac{3 - 20 y}{7} = 11 : y = - \frac{37}{10}

For

x = - \frac{- 1 + 2 y}{7}

Substitute

y = - \frac{37}{10}

x = - \frac{- 1 + 2 ( - \frac{37}{10} )}{7}

- \frac{- 1 + 2 ( - \frac{37}{10} )}{7} = \frac{6}{5}

x = \frac{6}{5}

The solutions to the system of equations are:

x = \frac{6}{5}, y = - \frac{37}{10}

4 x + 3 y = 17, 3 x - 4 y = - 6

x - y = 7, 2 y + 3 x = 12

2 p + 3 q - 4 = 3, p - 2 q - 19 = 0

x - 4 y = 2, 3 x + y = 1

(i) 2 x - y = - 2, x + 5 y = 5
