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

Solution

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

Solution

x = - 1, y = - 2

Solution steps

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

Isolate

x

for

- x + 2 y = - 3 : x = 3 + 2 y

Substitute

x = 3 + 2 y

[5 (3 + 2 y) - 2 y = - 1]

Simplify

[15 + 8 y = - 1]

Isolate

y

for

15 + 8 y = - 1 : y = - 2

For

x = 3 + 2 y

Substitute

y = - 2

x = 3 + 2 (- 2)

3 + 2 (- 2) = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 2
