To solve this equation, assume a range of values for x (say from -3 to +3). Substitute the value of x in the given equation to calculate the corresponding value of y. Repeat the procedure for each value of x in the range. Plot the set of values on a graph.

The y value of the point where the graph cuts the y-axis is the y-intercept.

To calculate the value of y when x = 16

5(16) + 4y = 12

4y = -68

y = -17
