Betty correctly determined that the ordered pair (–3, 5) is a solution to the system of linear equations and x + 4y = 17. Based on this information, which statement is correct? (–3, 5) satisfies neither the equation 6x + 5y = 7 nor the equation x + 4y = 17. (–3, 5) satisfies the equation 6x + 5y = 7 but not the equation x + 4y = 17. (–3, 5) satisfies the equation x + 4y = 17 but not the equation 6x + 5y = 7. (–3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.

Answer:

D. (–3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.

Explanation:

The given equations are:


6x +5y=7

and


x+4y=17


Betty correctly determined that the ordered pair
(-3,5) is a solution by substituting it into both equations.

Betty's work will look like this;

First Equation:


6(-3) +5(5)=7



-18 +25=7

This statement is True.

Second equation;


-3+4(5)=17



-3+20=17

This is also TRUE

Hence the correct answer is

D. (–3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.
