-3x-6y=-27,3x-y=20

Solution

- 3 x - 6 y = - 27, 3 x - y = 20

Solution

x = 7, y = 1

Solution steps

[- 3 x - 6 y = - 27 3 x - y = 20]

Isolate

x

for

- 3 x - 6 y = - 27 : x = 9 - 2 y

Substitute

x = 9 - 2 y

[3 (9 - 2 y) - y = 20]

Simplify

[27 - 7 y = 20]

Isolate

y

for

27 - 7 y = 20 : y = 1

For

x = 9 - 2 y

Substitute

y = 1

x = 9 - 2 \cdot 1

Simplify

x = 7

The solutions to the system of equations are:

x = 7, y = 1

Popular Examples

0.2 y = - 2.5, x = 1

3 x + y = 2, 6 x + 2 y = 4

5(x+2y)=6,y+105x+2y=20

5 (x + 2 y) = 6, y + 105 x + 2 y = 20

y - 3 x = 0, x = 2

x+5y-2(x+3y)=6,x-2y=-3

x + 5 y - 2 (x + 3 y) = 6, x - 2 y = - 3
