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

Solution

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

Solution

x = 2, y = - 2

Solution steps

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

Isolate

x

for

x + 3 y = - 4 : x = - 4 - 3 y

Substitute

x = - 4 - 3 y

[4 (- 4 - 3 y) + 2 y = 4]

Simplify

[- 16 - 10 y = 4]

Isolate

y

for

- 16 - 10 y = 4 : y = - 2

For

x = - 4 - 3 y

Substitute

y = - 2

x = - 4 - 3 (- 2)

- 4 - 3 (- 2) = 2

x = 2

The solutions to the system of equations are:

x = 2, y = - 2

Popular Examples

x - 5 y = 6 x - 8, y = 3

5x+3y+17=4,x+y+15=0

5 x + 3 y + 17 = 4, x + y + 15 = 0

5 x - 8 x = 5, x = 80 x

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

8x+6y=10,-3x+6y=-12

8 x + 6 y = 10, - 3 x + 6 y = - 12
