Andrea is 6 years younger than Tony. In two years, Tony will be three times as old as Andrea. Let a be Tony’s current age. Which of these linear equations can be used to find Andrea’s and Tony’s current ages?(1 point)
Responses
a+2=3(a+6+2)
a plus 2 equals 3 left parenthesis a plus 6 plus 2 right parenthesis
a=3(a+2)
a equals 3 left parenthesis a plus 2 right parenthesis
a+2=3(a−6+2)
a plus 2 equals 3 left parenthesis a minus 6 plus 2 right parenthesis
3(a+2)=a−6+2
3(a+2)=a-6+2

you are a lie. i posted the same question twice and you gave me 2 different answers. give me the REAL answer and prove its real.
I apologize for the confusion. The correct equation to find Andrea's and Tony's current ages can be written as:
a - 6 = (a + 2)/3
This equation represents the fact that Andrea is 6 years younger than Tony and in two years, Tony will be three times as old as Andrea.
You can simplify the equation further if needed.
