Expert Answer:

Let's say you have two linear equations,

ax + by = c


dx + ey = f.

rearrange them as,

y = -ax/b + c/b


y = -dx/e + f/e.

Then selected values of x from 0, 1, 2, and calculate corresponding values of y from both equations, and plot on the graph. The intersection of the two lines gives the solution to the linear equations.
