12x-16y=-2,4y^8x+16y=64

12 x - 16 y = - 2, 4 y^{8} x + 16 y = 64

(x = 1.53648 \dots, y = 1.27736 \dots)

Solution steps

[12 x - 16 y = - 2 4 y^{8} x + 16 y = 64]

Isolate

x

for

12 x - 16 y = - 2 : x = \frac{- 1 + 8 y}{6}

Plug the solutions

x = \frac{- 1 + 8 y}{6}

into

4 y^{8} x + 16 y = 64

For

4 y^{8} x + 16 y = 64

, subsitute

x

with

\frac{- 1 + 8 y}{6} : y \approx 1.27736 \dots

Plug the solutions

y = 1.27736 \dots

into

12 x - 16 y = - 2

For

12 x - 16 y = - 2

, subsitute

y

with

1.27736 \dots : x = 1.53648 \dots

Verify solutions by plugging them into the original equations

Therefore, the final solution for

12 x - 16 y = - 2, 4 y^{8} x + 16 y = 64

(x = 1.53648 \dots, y = 1.27736 \dots)

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

x - 3 y = - 12, 2 x + 3 y = 21

3 x + y - 11 = 0, 5 x - y - 13 = 0

5 x - 4 y = 12, 2 x - 4 y = 6

- 13 y + 11 x = - 163, - 8 x + 7 y = 94
