Elimination Method:

The system of equations are

Equation (1)

   Equation (2)

Apply division property of equality: Divide each side by 0.25.

Rearrange the terms using commutative property of addition: a + b = b + a.

         Equation (2)

Since the coefficients of p,q-terms and constant are additive inverses, these terms can be

elimanted by adding equations.

Write the equations in column form and add the corresponding columns. \ \

Because the equation 0 = 0 is true, this system has inifinite solutions.

The system has inifinite solutions.
