Step-by-step explanation:

IF we think about it, we ned to realize that the only two numbers that would possible give us a four digit number (PART) are 0 and 1. (All other options give us fire digit number after numliplying by 9). Then we must remmember that each digit has to be a different digit. So, if we put 1 in the place of R, we would have to put 2 in the place of T because we can not use numbers twice. Therefore, the only solution would be if it is o.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

2,160 π
