3x+4y=17,2x-5y=19

Solution

3 x + 4 y = 17, 2 x - 5 y = 19

Solution

x = 7, y = - 1

Solution steps

[3 x + 4 y = 17 2 x - 5 y = 19]

Isolate

x

for

3 x + 4 y = 17 : x = \frac{17 - 4 y}{3}

Substitute

x = \frac{17 - 4 y}{3}

[2 \cdot \frac{17 - 4 y}{3} - 5 y = 19]

Simplify

[\frac{34 - 23 y}{3} = 19]

Isolate

y

for

\frac{34 - 23 y}{3} = 19 : y = - 1

For

x = \frac{17 - 4 y}{3}

Substitute

y = - 1

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

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

x = 7

The solutions to the system of equations are:

x = 7, y = - 1
