3x+2y=2,x-y=9

Solution

3 x + 2 y = 2, x - y = 9

Solution

x = 4, y = - 5

Solution steps

[3 x + 2 y = 2 x - y = 9]

Isolate

x

for

3 x + 2 y = 2 : x = \frac{2 - 2 y}{3}

Substitute

x = \frac{2 - 2 y}{3}

[\frac{2 - 2 y}{3} - y = 9]

Simplify

[\frac{2 - 5 y}{3} = 9]

Isolate

y

for

\frac{2 - 5 y}{3} = 9 : y = - 5

For

x = \frac{2 - 2 y}{3}

Substitute

y = - 5

x = \frac{2 - 2 ( - 5 )}{3}

\frac{2 - 2 ( - 5 )}{3} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = - 5

Popular Examples

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

20x+10y=50,0y^{40}x-50y=300

20 x + 10 y = 50, 0 y^{40} x - 50 y = 300

3x-2y=10,2x+3y=10

3 x - 2 y = 10, 2 x + 3 y = 10

4x-11y=-3,2x+5y=21

4 x - 11 y = - 3, 2 x + 5 y = 21

x+y+z=9,2x-3y+4z=13,3x+4y+5z=40

x + y + z = 9, 2 x - 3 y + 4 z = 13, 3 x + 4 y + 5 z = 40
