Question

Solve the system by graphing. 2x – 10y = - 30 2x + 5y = 30

Answer 1

Firstly, write the first equaton.

2x-10y=-30

now, we can calculate the both the point of the equation by putting zero the value of x and y each at a time.

So, A(0, 3), and B(-15,0)

Now, second equation

now, we can calculate the both the point of the equation by putting zero the value of x and y each at a time.

So, C(0, 6), and D(15,0)

Now, put the value in the graph.

Now, the intersection point will give the value of x and y.

The value of the x=5, and y=4.
