Solve the following simultaneous equations by drawing graphs, (a) x +y=7 and y=x-3
b) x + y = 8 and x=y

a) x = 5 and y = 2

b) x = 4 and y = 4

Step-by-step explanation:

Here, we want to solve the simultaneous equations by graphing

We shall be using an external graphing tool for this

The point at which the lines intersect represent the solution to the equation

please check attachment for the plots

For the first equation, we have the solution as;

x = 5 and y = 2

For the second, we have;

x = 4 and y = 4
