-2x-7y=25,-2x-5y=19

- 2 x - 7 y = 25, - 2 x - 5 y = 19

x = - 2, y = - 3

Solution steps

[- 2 x - 7 y = 25 - 2 x - 5 y = 19]

Isolate

x

for

- 2 x - 7 y = 25 : x = - \frac{25 + 7 y}{2}

Substitute

x = - \frac{25 + 7 y}{2}

[- 2 (- \frac{25 + 7 y}{2}) - 5 y = 19]

Simplify

[25 + 2 y = 19]

Isolate

y

for

25 + 2 y = 19 : y = - 3

For

x = - \frac{25 + 7 y}{2}

Substitute

y = - 3

x = - \frac{25 + 7 ( - 3 )}{2}

- \frac{25 + 7 ( - 3 )}{2} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = - 3

2 x + y = 5, 0.3 x + 2 y = 7

a = 570, a = 7, c = 8

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

10 y + 7 x = 2, 9 - 5 y - 9 x = 2

3 x + 2 y = 18, 13 x - 14 y + 58 = 0
