### Re: System of equations

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

### Re: System of equations

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.
