x-3y=-12,2x+3y=21

Solution

x - 3 y = - 12, 2 x + 3 y = 21

Solution

x = 3, y = 5

Solution steps

[x - 3 y = - 12 2 x + 3 y = 21]

Isolate

x

for

x - 3 y = - 12 : x = - 12 + 3 y

Substitute

x = - 12 + 3 y

[2 (- 12 + 3 y) + 3 y = 21]

Simplify

[- 24 + 9 y = 21]

Isolate

y

for

- 24 + 9 y = 21 : y = 5

For

x = - 12 + 3 y

Substitute

y = 5

x = - 12 + 3 \cdot 5

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 5

Popular Examples

3x+y-11=0,5x-y-13=0

3 x + y - 11 = 0, 5 x - y - 13 = 0

5x-4y=12,2x-4y=6

5 x - 4 y = 12, 2 x - 4 y = 6

-13y+11x=-163,-8x+7y=94

- 13 y + 11 x = - 163, - 8 x + 7 y = 94

x + 2 y = 5, - y = - 8

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

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