# In Exercises 39 to 42, use substitution to solve the system.Use Example 9 as a guide. y = 2 x + 3 and y = 3 x .

To determine

To Solve:

The system described by the equations y=2x+3 and y=3x 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.

2x+3 = 3x

Bring 3x to left hand side of the equation.

Bring 3 to right hand side of the equation.

Then,

2x-3x  = -3
