12x+15y=3,4-6x+5y=3

12 x + 15 y = 3, 4 - 6 x + 5 y = 3

x = \frac{1}{5}, y = \frac{1}{25}

Solution steps

[12 x + 15 y = 3 4 - 6 x + 5 y = 3]

Isolate

x

for

12 x + 15 y = 3 : x = \frac{1 - 5 y}{4}

Substitute

x = \frac{1 - 5 y}{4}

[4 - 6 \cdot \frac{1 - 5 y}{4} + 5 y = 3]

Simplify

[\frac{25 y - 3}{2} + 4 = 3]

Isolate

y

for

\frac{25 y - 3}{2} + 4 = 3 : y = \frac{1}{25}

For

x = \frac{1 - 5 y}{4}

Substitute

y = \frac{1}{25}

x = \frac{1 - 5 \cdot \frac{1}{25}}{4}

\frac{1 - 5 \cdot \frac{1}{25}}{4} = \frac{1}{5}

x = \frac{1}{5}

The solutions to the system of equations are:

x = \frac{1}{5}, y = \frac{1}{25}

20 a + 9 b = 63, 15 a + 4 b = 39

9 x + 3 y + 12 = 6, x - 3 y + 10 = 0

10 x - 3 y = 36, 2 x + 5 y = - 4

x = 2 t, y = 4 t^{3} - 1

x - y = 4, x + y = 5
