3x+y=11,2x+y=9

Solution

3 x + y = 11, 2 x + y = 9

Solution

x = 2, y = 5

Solution steps

[3 x + y = 11 2 x + y = 9]

Isolate

x

for

3 x + y = 11 : x = \frac{11 - y}{3}

Substitute

x = \frac{11 - y}{3}

[2 \cdot \frac{11 - y}{3} + y = 9]

Simplify

[\frac{22 + y}{3} = 9]

Isolate

y

for

\frac{22 + y}{3} = 9 : y = 5

For

x = \frac{11 - y}{3}

Substitute

y = 5

x = \frac{11 - 5}{3}

\frac{11 - 5}{3} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 5

Popular Examples

13x-6y=2,2x=y+6

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

x + y = 24, 2 x - y = - 6

12(x+2y)-8(2x+y)=2,(5x-6y)20(x-4y)=-10

12 (x + 2 y) - 8 (2 x + y) = 2, (5 x - 6 y) 20 (x - 4 y) = - 10

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

x - y = 8, 3 x - 3 y = 16
