x-3y=5,2x+4y=0

Solution

x - 3 y = 5, 2 x + 4 y = 0

Solution

x = 2, y = - 1

Solution steps

[x - 3 y = 5 2 x + 4 y = 0]

Isolate

x

for

x - 3 y = 5 : x = 5 + 3 y

Substitute

x = 5 + 3 y

[2 (5 + 3 y) + 4 y = 0]

Simplify

[10 + 10 y = 0]

Isolate

y

for

10 + 10 y = 0 : y = - 1

For

x = 5 + 3 y

Substitute

y = - 1

x = 5 + 3 (- 1)

5 + 3 (- 1) = 2

x = 2

The solutions to the system of equations are:

x = 2, y = - 1

Popular Examples

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

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

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

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

2x+y+z=1,6x+2y+z=-1,-2x+2y+z=7

2 x + y + z = 1, 6 x + 2 y + z = - 1, - 2 x + 2 y + z = 7

x+y+z=6,x-y+z=2,x-z=-2

x + y + z = 6, x - y + z = 2, x - z = - 2
