x+15y=3,1x-2y=-3

x + 15 y = 3, 1 x - 2 y = - 3

x = - \frac{39}{17}, y = \frac{6}{17}

Solution steps

[x + 15 y = 3 1 \cdot x - 2 y = - 3]

Isolate

x

for

x + 15 y = 3 : x = 3 - 15 y

Substitute

x = 3 - 15 y

[1 \cdot (3 - 15 y) - 2 y = - 3]

Simplify

[3 - 17 y = - 3]

Isolate

y

for

3 - 17 y = - 3 : y = \frac{6}{17}

For

x = 3 - 15 y

Substitute

y = \frac{6}{17}

x = 3 - 15 \cdot \frac{6}{17}

3 - 15 \cdot \frac{6}{17} = - \frac{39}{17}

x = - \frac{39}{17}

The solutions to the system of equations are:

x = - \frac{39}{17}, y = \frac{6}{17}

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

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

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

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

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