x+y=1,5x-y=9

Solution

x + y = 1, 5 x - y = 9

Solution

x = \frac{5}{3}, y = - \frac{2}{3}

Solution steps

[x + y = 1 5 x - y = 9]

Isolate

x

for

x + y = 1 : x = 1 - y

Substitute

x = 1 - y

[5 (1 - y) - y = 9]

Simplify

[5 - 6 y = 9]

Isolate

y

for

5 - 6 y = 9 : y = - \frac{2}{3}

For

x = 1 - y

Substitute

y = - \frac{2}{3}

x = 1 - (- \frac{2}{3})

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

x = \frac{5}{3}

The solutions to the system of equations are:

x = \frac{5}{3}, y = - \frac{2}{3}

Popular Examples

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

-3x+5y=5,3x+2y=23

- 3 x + 5 y = 5, 3 x + 2 y = 23

x+y=25,0x+y=400

x + y = 25, 0 x + y = 400

x+y=-7,3x-5y=11

x + y = - 7, 3 x - 5 y = 11

3x+7y=5,2x-4y=-9

3 x + 7 y = 5, 2 x - 4 y = - 9
