x+3y=-8,4x-5y=2

Solution

x + 3 y = - 8, 4 x - 5 y = 2

Solution

x = - 2, y = - 2

Solution steps

[x + 3 y = - 8 4 x - 5 y = 2]

Isolate

x

for

x + 3 y = - 8 : x = - 8 - 3 y

Substitute

x = - 8 - 3 y

[4 (- 8 - 3 y) - 5 y = 2]

Simplify

[- 32 - 17 y = 2]

Isolate

y

for

- 32 - 17 y = 2 : y = - 2

For

x = - 8 - 3 y

Substitute

y = - 2

x = - 8 - 3 (- 2)

- 8 - 3 (- 2) = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = - 2

x - 3 y - 3 = 3, x - 9 y - 2 = 0

2x+y=-10,x-3y=2

2 x + y = - 10, x - 3 y = 2

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

4 x + 2 y = 8, 3 x - y = 1

4x-4=10,5x+2y=14

4 x - 4 = 10, 5 x + 2 y = 14
