8y-8x=30,50x-12y=4

8 y - 8 x = 30, 50 x - 12 y = 4

x = \frac{49}{38}, y = \frac{383}{76}

Solution steps

[8 y - 8 x = 30 50 x - 12 y = 4]

Isolate

y

for

8 y - 8 x = 30 : y = \frac{15 + 4 x}{4}

Substitute

y = \frac{15 + 4 x}{4}

[50 x - 12 \cdot \frac{15 + 4 x}{4} = 4]

Simplify

[38 x - 45 = 4]

Isolate

x

for

38 x - 45 = 4 : x = \frac{49}{38}

For

y = \frac{15 + 4 x}{4}

Substitute

x = \frac{49}{38}

y = \frac{15 + 4 \cdot \frac{49}{38}}{4}

\frac{15 + 4 \cdot \frac{49}{38}}{4} = \frac{383}{76}

y = \frac{383}{76}

The solutions to the system of equations are:

x = \frac{49}{38}, y = \frac{383}{76}

x + 3 y = 6, 2 x - 3 y = 12

3 x - y = - 3, 2 x + y = 8

3 x + 5 y = 21, 4 x - 2 y = 2

x + y = 5, 3 x + y = 18

x + 4 y = - 25, - 10 x - 5 y = 5
