To solve the equation 6x - 7y = 18 for y, you can start by isolating y on one side of the equation. To do this, you can add 7y to both sides of the equation:
6x - 7y + 7y = 18 + 7y
6x = 18 + 7y
Next, divide both sides of the equation by 7:
6x/7 = 18/7 + 7y/7
x = 3 + y
So the solution is y = 3 - x
This is the final solution for y in the equation 6x - 7y = 18
