x-2y=8,2x+y=6

Solution

x - 2 y = 8, 2 x + y = 6

Solution

x = 4, y = - 2

Solution steps

[x - 2 y = 8 2 x + y = 6]

Isolate

x

for

x - 2 y = 8 : x = 8 + 2 y

Substitute

x = 8 + 2 y

[2 (8 + 2 y) + y = 6]

Simplify

[16 + 5 y = 6]

Isolate

y

for

16 + 5 y = 6 : y = - 2

For

x = 8 + 2 y

Substitute

y = - 2

x = 8 + 2 (- 2)

8 + 2 (- 2) = 4

x = 4

The solutions to the system of equations are:

x = 4, y = - 2

Popular Examples

3x+2y=-1,5x+y=4

3 x + 2 y = - 1, 5 x + y = 4

2x+3y=2,-5x+12y=1

2 x + 3 y = 2, - 5 x + 12 y = 1

x-y=14,3x+2y=22

x - y = 14, 3 x + 2 y = 22

4(2x+y)+5(2x-y)=17,3(2x+y)-(2x-y)=8

4 (2 x + y) + 5 (2 x - y) = 17, 3 (2 x + y) - (2 x - y) = 8

y + 12 x - 2 y = 4, x = 2
