Respuesta :
5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17 <-----answer
Answer:
D. (–3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.
Step-by-step explanation:
The given equations are:
[tex]6x +5y=7[/tex]
and
[tex]x+4y=17[/tex]
Betty correctly determined that the ordered pair [tex](-3,5)[/tex] is a solution by substituting it into both equations.
Betty's work will look like this;
First Equation:
[tex]6(-3) +5(5)=7[/tex]
[tex]-18 +25=7[/tex]
This statement is True.
Second equation;
[tex]-3+4(5)=17[/tex]
[tex]-3+20=17[/tex]
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.
