7 (1)/(3) + n = 10 (3)/(8) \\


(21 + 1)/(3) + n = (80 + 3)/(8) \\


(22)/(3) + n = (83)/(8) \\

Subtract sides 22 / 3


- (22)/(3) + (22)/(3) + n = - (22)/(3) + (83)/(8) \\


n = (83)/(8) - (22)/(3) \\


n = (83 * 3)/(8 * 3) - (22 * 8)/(3 * 8) \\


n = (249)/(24) - (176)/(24) \\


n = (249 - 176)/(24) \\


n = (73)/(24) \\


n = (72 + 1)/(24) \\


n = 3 (1)/(24) \\
