x+157x+15y=2x^2x,y=7

x + 157 x + 15 y = 2 x^{2} x, y = 7

x = - 0.66833 \dots, x = - 8.53516 \dots, x = 9.20349 \dots, y = 7 y = 7 y = 7

Solution steps

[x + 157 x + 15 y = 2 x^{2} x y = 7]

Plug the solutions

y = 7

into

x + 157 x + 15 y = 2 x^{2} x

For

x + 157 x + 15 y = 2 x^{2} x

, subsitute

y

with

7 : x \approx - 0.66833 \dots, x \approx - 8.53516 \dots, x \approx 9.20349 \dots

Verify solutions by plugging them into the original equations

Therefore, the final solutions for

x + 157 x + 15 y = 2 x^{2} x, y = 7

are

x = - 0.66833 \dots, x = - 8.53516 \dots, x = 9.20349 \dots, y = 7 y = 7 y = 7

y^{2} = 2 x, y = x - 4

x y = - 4, 3 x + 4 y = - 22

x^{2} + y^{2} + 6 x + 2 y = 0, x + y = - 8

y^{2} = x + 1, y = x - 1

6 x + 3 y = 6, x y^{2} x + 4 y = 5 x y
