Find all possible values of the digits Y, E, A, R if - EEE + AA - R = 1234, and different letters represent different digits. HELP QUICK! 100 PTS

Y=2, E=9, A=1, R=0

Step-by-step explanation:

1000Y+100Y+10Y+Y-100E-10E-E+10A+A-R=1234

1111Y-111E+11A-1R=1234

Y cannot be 1, and it cannot be greater than 2, since the other digits could not possibly make it add up to 1234. This means that Y must be 2:

2222-111E+11A-R=1234

In this case, E would have to be 9 to make it possible for this to have a solution, by bringing it down to 1223.

1223+11A-R=1234

1223+11=1234, meaning that A must be 1 and that R must be 0. Hope this helps!

you never say the total so we cant find the percentage used for petrol
