Let J be the amount Jin raised, D be the amount Deb raised, and B be the amount Brishir raised
1). J + B + D = 135.78
2). D = B - 34
3). B = J + 29
Substitute Equations 2 and 3 into Equation 1:
4) J + (J + 29) + (B - 34) = 135.78
Substitute Equation 3 into 4:
J + (J + 29) + ((J + 29) - 34) = 135.78
3J = 135.78 - 29 - 29 + 34 = 111.78
J = 37.26
