x+y=6,2x-3y=27

Solution

x + y = 6, 2 x - 3 y = 27

Solution

x = 9, y = - 3

Solution steps

[x + y = 6 2 x - 3 y = 27]

Isolate

x

for

x + y = 6 : x = 6 - y

Substitute

x = 6 - y

[2 (6 - y) - 3 y = 27]

Simplify

[12 - 5 y = 27]

Isolate

y

for

12 - 5 y = 27 : y = - 3

For

x = 6 - y

Substitute

y = - 3

x = 6 - (- 3)

Simplify

x = 9

The solutions to the system of equations are:

x = 9, y = - 3

Popular Examples

2 x + y = 8, x - y = 1

27x+54y=21,6-22.5x+45y=90

27 x + 54 y = 21, 6 - 22.5 x + 45 y = 90

8y-8x=30,50x-12y=4

8 y - 8 x = 30, 50 x - 12 y = 4

x+3y=6,2x-3y=12

x + 3 y = 6, 2 x - 3 y = 12

3 x - y = - 3, 2 x + y = 8
