We have two equations:

Y - 5x = -18 .....(1)

3y = -9x + 18 .....(2)

We can use equation (2) to solve for y in terms of x:

3y = -9x + 18

y = (-9/3)x + 18/3

y = -3x + 6

Now we can substitute this expression for y into equation (1):

Y - 5x = -18

(-3x + 6) - 5x = -18

-8x + 6 = -18

Subtracting 6 from both sides:

-8x = -24

Dividing both sides by -8:

x = 3

Now we can use this value of x to find y:

y = -3x + 6

y = -3(3) + 6

y = -3

Therefore, the solution to the system of equations is (x, y) = (3, -3).
