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

Solution

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

Solution

x = 4, y = - 1

Solution steps

[x + 2 y = 2 x - 2 y = 6]

Isolate

x

for

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

Substitute

x = 2 - 2 y

[2 - 2 y - 2 y = 6]

Simplify

[2 - 4 y = 6]

Isolate

y

for

2 - 4 y = 6 : y = - 1

For

x = 2 - 2 y

Substitute

y = - 1

x = 2 - 2 (- 1)

2 - 2 (- 1) = 4

x = 4

The solutions to the system of equations are:

x = 4, y = - 1

Popular Examples

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

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

((x+3))/y =2,((y+6))/x =-1

\frac{( x + 3 )}{y} = 2, \frac{( y + 6 )}{x} = - 1

0 k = \frac{1}{42}, x = 16

3x-2y=5,2x+3y=17

3 x - 2 y = 5, 2 x + 3 y = 17
