5x+3y=9,2x+y=4

Solution

5 x + 3 y = 9, 2 x + y = 4

Solution

x = 3, y = - 2

Solution steps

[5 x + 3 y = 9 2 x + y = 4]

Isolate

x

for

5 x + 3 y = 9 : x = \frac{9 - 3 y}{5}

Substitute

x = \frac{9 - 3 y}{5}

[2 \cdot \frac{9 - 3 y}{5} + y = 4]

Simplify

[\frac{18 - y}{5} = 4]

Isolate

y

for

\frac{18 - y}{5} = 4 : y = - 2

For

x = \frac{9 - 3 y}{5}

Substitute

y = - 2

x = \frac{9 - 3 ( - 2 )}{5}

\frac{9 - 3 ( - 2 )}{5} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 2

Popular Examples

5x+9y=12,4x-3y=8

5 x + 9 y = 12, 4 x - 3 y = 8

x+7y=-2,3x+y=34

x + 7 y = - 2, 3 x + y = 34

5x+3y=26,10x-y=38

5 x + 3 y = 26, 10 x - y = 38

7y+10x-8=2,y-5x-18=0

7 y + 10 x - 8 = 2, y - 5 x - 18 = 0

2x+y=4,2x-2y=10

2 x + y = 4, 2 x - 2 y = 10
