5x+y=17,3x-y=7

Solution

5 x + y = 17, 3 x - y = 7

Solution

x = 3, y = 2

Solution steps

[5 x + y = 17 3 x - y = 7]

Isolate

x

for

5 x + y = 17 : x = \frac{17 - y}{5}

Substitute

x = \frac{17 - y}{5}

[3 \cdot \frac{17 - y}{5} - y = 7]

Simplify

[\frac{51 - 8 y}{5} = 7]

Isolate

y

for

\frac{51 - 8 y}{5} = 7 : y = 2

For

x = \frac{17 - y}{5}

Substitute

y = 2

x = \frac{17 - 2}{5}

\frac{17 - 2}{5} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 2

Popular Examples

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

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)
