Answer 1

$8x + 21x = x(8 + 21) = x29 = 29x \\ 326y + 99y = 425y \\ 9.8b + b = 9.8b + 1b = 10.8b \\ 31t - 9.1t= 21.9t \\ 6x - 5x + x = 6x - 4x = 2x \\ 78a - 49a = 29a \\ 15.3x - 8.8x = 6.5x \\ 26m - m = 26m - 1m = 25m \\ 2y + 19y + y = 21y + 1y = 22y \\ 7b + b - 8b = 7b - 1b - 8b = 8b - 8b = 0b = 0$
