4x+10y=-4,6x-15y=0

4 x + 10 y = - 4, 6 x - 15 y = 0

x = - \frac{1}{2}, y = - \frac{1}{5}

Solution steps

[4 x + 10 y = - 4 6 x - 15 y = 0]

Isolate

x

for

4 x + 10 y = - 4 : x = - \frac{5 y + 2}{2}

Substitute

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

[6 (- \frac{5 y + 2}{2}) - 15 y = 0]

Simplify

[- 30 y - 6 = 0]

Isolate

y

for

- 30 y - 6 = 0 : y = - \frac{1}{5}

For

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

Substitute

y = - \frac{1}{5}

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

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

x = - \frac{1}{2}

The solutions to the system of equations are:

x = - \frac{1}{2}, y = - \frac{1}{5}

8 s = 1, 3 t = 26.31, t = 1

2 x + 5 y = - 11, 2 x - y = 11

2 x - y = 7, x + 2 y = 6

64 m - 45 n = 289, 45 m - 64 n = 365

x + y = 7, 3 x - 2 y = 11
