You can graph multiple equations in one plot by merely superimposing them. You plot the x values against the corresponding y values. Usually, you are given an equation in this form y=f(x), where f(x) is a polynomial containing a variable of x. You assign arbitrary values of x, to get the y values and plot them together as one data point.
The point at which the graphs intersect each other is the solution of the problem.

Answer:
Part a) 2.36 quarts
Part b) 47.2%
Step-by-step explanation:
Let
x ---> percentage of the resulting mixture that is antifreeze
Remember that
we know that
3 quarts of a solution multiplied by 0.22 (percentage in decimal form) plus 2 quarts of a solution multiplied by 0.85 (percentage in decimal form), must be equal to 5 quarts of a solution multiplied by x (percentage of the resulting mixture)
so
The linear equation that represent this situation is
solve for x
Convert to percentage
therefore
The percentage of the resulting mixture that is antifreeze is 47.2%
To find out how many quarts of antifreeze are in the resulting mixture, multiply the total quarts of the resulting mixture by the percentage in decimal form
