The y value of 18 is given in the table. For a linear equation with two variables,  there are an infinite number of solutions. The concept here is to be given one of the values for either x, or y and find the other value that makes the equation true. For example, with this equation 5x+3 = y, we could say if x is 12, what is the y value that makes the equation true. So we substitute a 12 in for x and get 5(12)+3=y, which leads to 63=y. Hope that helps out.

The procedure would still be the same. For example if I have the equation: (1/3)x + 3 = y, I can choose something for x and solve for y (and vice versa). Try it out, let x=3, and you will get y=4. So x=3 y=4, or (3, 4) would be one solution to the new equation.
