System of equations

[kate]

Calculate:

|2x² - 3xy - x - 4 = 0
|x² - 9xy + 18y² = 0

[Mathmaven53]

factor second equation.

(x - 3 y)(x - 6y) = 0

x = 3y

Substitute into first equation and solve for y

Or x = 6 y
Substitute into first equation and solve for y

By the factorizing method, we will solve and calculate the value of x.
by solving equation second, we will get the value of x.
Let the value of x we get is "3" so now we will put this value of x into the first equation and find out the value of y.

Hope..... it will be helpful for you to solve it now.
