17x+10y=61,5x+10y=4

17 x + 10 y = 61, 5 x + 10 y = 4

x = \frac{19}{4}, y = - \frac{79}{40}

Solution steps

[17 x + 10 y = 61 5 x + 10 y = 4]

Isolate

x

for

17 x + 10 y = 61 : x = \frac{61 - 10 y}{17}

Substitute

x = \frac{61 - 10 y}{17}

[5 \cdot \frac{61 - 10 y}{17} + 10 y = 4]

Simplify

[\frac{305 + 120 y}{17} = 4]

Isolate

y

for

\frac{305 + 120 y}{17} = 4 : y = - \frac{79}{40}

For

x = \frac{61 - 10 y}{17}

Substitute

y = - \frac{79}{40}

x = \frac{61 - 10 ( - \frac{79}{40} )}{17}

\frac{61 - 10 ( - \frac{79}{40} )}{17} = \frac{19}{4}

x = \frac{19}{4}

The solutions to the system of equations are:

x = \frac{19}{4}, y = - \frac{79}{40}

2 x + y + z = 7, x - y - z = - 4, 3 x + 2 y + z = 10

2 x + y = - 4, 5 x - 3 y = 1

y 13 = 1, z 13 = 10, 0.03 + j 0.09 = 3.33 - j 10

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

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