Question

Which of the following are steps in the process in solving application problems using the two-order system?

Assign two variables for the unknowns.

Make a guess for the value of the variables.

Write two equations using the assigned variables.

Make another guess, based on the results of the first guess. Solve the pair of equations.

Answer 1

Explanation:

Assign two variables for the unknowns.

Write two equations using the assigned variables.

Solve the pair of equations.

Answer 2

Options A, C and E are correct.

Explanation:

a. Assign two variables for the unknowns.- Firstly we read the problem and then assign values like (x and y) to the unknown entities.

c. Write two equations using the assigned variables. - After the first step, we get few equations to be solved. These equations are based on the assigned values from step 1.

e. Solve the pair of equations. - Finally we solve these equations to get the variable values.
