5x-2y=17,8x+5y=19

Solution

5 x - 2 y = 17, 8 x + 5 y = 19

Solution

x = 3, y = - 1

Solution steps

[5 x - 2 y = 17 8 x + 5 y = 19]

Isolate

x

for

5 x - 2 y = 17 : x = \frac{17 + 2 y}{5}

Substitute

x = \frac{17 + 2 y}{5}

[8 \cdot \frac{17 + 2 y}{5} + 5 y = 19]

Simplify

[\frac{136 + 41 y}{5} = 19]

Isolate

y

for

\frac{136 + 41 y}{5} = 19 : y = - 1

For

x = \frac{17 + 2 y}{5}

Substitute

y = - 1

x = \frac{17 + 2 ( - 1 )}{5}

\frac{17 + 2 ( - 1 )}{5} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 1

Popular Examples

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

2x-7y=39,3x+5y=31

2 x - 7 y = 39, 3 x + 5 y = 31

8x-5y=-21,7y+4x=-1

8 x - 5 y = - 21, 7 y + 4 x = - 1

4x+3y=1,8e^6x+y=13

4 x + 3 y = 1, 8 e^{6} x + y = 13

126x+88y=18,72x+48y=10

126 x + 88 y = 18, 72 x + 48 y = 10
