Question

What are two ways to verify that your solutions are correct?

Check all that apply.

A. Try values for variables that don't match
B. Graph the equations and see where they meet
C. Substitute one variable's value for the other
D. Substitute back into both equations

Answer 1

B. Graph the equations and see where they meet.

D. Substitute back into both equations.

Explanation:

The two ways to verify that your solutions are correct are:

B. Graph the equations and see where they meet - Graphing is a very accurate and precise way to fetch solutions.

D. Substitute back into both equations - we can do this to cross check our solutions. This way makes sure that the solution is correct.

Answer 2

The correct answers among the choices presented above are options B and D. Two ways to verify that solutions are correct are done by graphing the equations and see where they meet and by substitute back into both equations. The intersection of the graph signifies the solution. Also, when after substituting the solutions to both equations and they satisfy the equality then it is correct.
