PROBLEM:

Solve the given system of linear equations:

• A. {-3, -4}
• B. {3, 4}
• C. {4, 3}
• D. {-4, -3}

ANSWER:

The correct answer is choice B. The solution set to the given system of linear equations in {3, 4}.

SOLUTION:

We will be using substitution method to solve this system of linear equations.

» In the first equation, solve for y in terms of x.

» In the second equation, substitute the value of y to solve for x.

» In any of the two equations, substitute the value of x to solve for y.

Therefore, the solution set is {3, 4}. The correct answer is choice B.
