Question

the value of a baseball card can be represented by the equation y equals 3x + 39 where X represents the number of years that Robert has on the card and why represents the total value in dollars of the card what was the value of the card when Robert originally purchased it $3 $13 $36.39​

Answer 1

Answer:

I need the values of either X or Y to solve this. I can solve for what X is though.

Step-by-step explanation:

A: X = -12

B: X =78

C: X = 12.13

I hope this helps you, but since both X and Y are unknown variables, you can't solve it, only simplify (which it already is.)
