In Exercises 39 to 42, use substitution to solve the system.Use Example 9 as a guide. y = a and y = b x + c .

To determine

To Solve:

The system described by the equations y=a and y=bx+c using the method of substitution.

Explanation

The steps to be followed to solve a system of equations are described below.

Write each equation in the form of y=mx+b.

Then equate the expressions for y.

Once the x-coordinate of the solution is known, substitute this value of x into either equation to find the value of y.

Since the given equations are in the form y=mx+b equate values for y.

a = bx + c

Bring c to the left hand side of the equation.

Then,

a-c = bx

Rewrite the equation a-cbx as,

bx = a-c.

Bring b to the right hand side of the equation.

So,

x=a-cb.

It is given that y=a
