when we add negative number to the positive number we just subtract the smaller number from the larger number and put the sign or the larger number after words
examples:- First

like here we put + in front of 3 as larger number 5 is positive
<h3>second</h3>

we put negative because 7 is larger then 5 and 7 is negative
According to the problem, it can be translated to
J + R = 97
J = 4 + 2R
solving these equations
J = 66
R = 31
