x-4y=3,2x-y=5

Solution

x - 4 y = 3, 2 x - y = 5

Solution

x = \frac{17}{7}, y = - \frac{1}{7}

Solution steps

[x - 4 y = 3 2 x - y = 5]

Isolate

x

for

x - 4 y = 3 : x = 3 + 4 y

Substitute

x = 3 + 4 y

[2 (3 + 4 y) - y = 5]

Simplify

[6 + 7 y = 5]

Isolate

y

for

6 + 7 y = 5 : y = - \frac{1}{7}

For

x = 3 + 4 y

Substitute

y = - \frac{1}{7}

x = 3 + 4 (- \frac{1}{7})

3 + 4 (- \frac{1}{7}) = \frac{17}{7}

x = \frac{17}{7}

The solutions to the system of equations are:

x = \frac{17}{7}, y = - \frac{1}{7}

Popular Examples

2x-y=12, 3/2 x+5y=4

2 x - y = 12, \frac{3}{2} x + 5 y = 4

x+2y+z=3,2x-3y+2z=-15,3x+6y-7z=59

x + 2 y + z = 3, 2 x - 3 y + 2 z = - 15, 3 x + 6 y - 7 z = 59

-3x+5y=2,7x-3y=1

- 3 x + 5 y = 2, 7 x - 3 y = 1

19x+3y=5,2x+y=(r+1)

19 x + 3 y = 5, 2 x + y = (r + 1)

3 x + 2 y = 8, x + 3 y = 5
