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

Solution

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

Solution

x = \frac{18}{5}, y = \frac{4}{5}

Solution steps

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

Isolate

x

for

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

Substitute

x = 2 + 2 y

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

Simplify

[4 + 5 y = 8]

Isolate

y

for

4 + 5 y = 8 : y = \frac{4}{5}

For

x = 2 + 2 y

Substitute

y = \frac{4}{5}

x = 2 + 2 \cdot \frac{4}{5}

2 + 2 \cdot \frac{4}{5} = \frac{18}{5}

x = \frac{18}{5}

The solutions to the system of equations are:

x = \frac{18}{5}, y = \frac{4}{5}

Popular Examples

x=(x)+(x)+x,x=4

x = (x) + (x) + x, x = 4

2.5 c = 41.3, a = 3

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

a + b = 1, 4 a - b = 2

x - y = 10, x + y = 2
