math question
$2 {y}^{3} \: \: \: + \: \: \: 4 {x}^{2 \: \: } - y \: = {x}^{6}$
​

Answer 1

Step-by-step explanation:

2y - x = 2

3y-4x = -2

Multiply the first equation by 4

8y - 4x = 8

3y - 4x = -2

Change the sign of the first equation

-8y +4x = -8

Add the two equation

-8y +4x = -8

3y - 4x = -2

Then, -5y = - 10

y = - 10/-5 = 2

put the value of y to the any of the above equation

3*2 -4*x = -2

4x = 6+2

4x = 8

x = 8/4 =2

x =2, y=2
