Linear Equations and Systems of Linear Equations

Which statement is true about the system (see photo)?

• There is one ordered pair that will both equations.

• There is no ordered pair that will satisfy both equations.

• There is infinitely many ordered pairs that will satisfy both equations.

• Equation 2 is obtained by multiplying each term in equation 1 by 3.

Dustin Zayd was tasked by his teacher to find an ordered pair that satisfies the given system (see photo). His answer is point (3, 4) is he correct?

• Yes, because he substituted the variable of x = 3 and y = 4 to the system of linear equations.

• Yes, because he yielded two true statements that makes a solution of the system of linear equations.

• No, because he did not follow the steps in evaluating system of linear equations in two variables.

• No, because the point (3, 4) does not satisfy the given system of linear equations in two variables.
