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

Solution

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

Solution

x = 4, y = 0

Solution steps

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

Isolate

x

for

2 x - 4 y = 8 : x = 2 (y + 2)

Substitute

x = 2 (y + 2)

[2 (y + 2) + 8 y = 4]

Simplify

[10 y + 4 = 4]

Isolate

y

for

10 y + 4 = 4 : y = 0

For

x = 2 (y + 2)

Substitute

y = 0

x = 2 (0 + 2)

Simplify

x = 4

The solutions to the system of equations are:

x = 4, y = 0

Popular Examples

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

x+2y=10,3x+4y=22

x + 2 y = 10, 3 x + 4 y = 22

x + y = 6, x - y = 8

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

x-5=1,3x-y=(12y)/2

x - 5 = 1, 3 x - y = \frac{12 y}{2}
