a) When 5 is added to a number, the result is \(-3\)
\( x + 5 = -3 \)
b) When 3 is added to a number, the result is 0
\( x + 3 = 0 \)

c) When 15 is subtracted from twice a number, the result is 12
\( 2a - 15 = 12 \)
d) When \(-8\) is subtracted from three times a number, the result is \(-5\)
\( 3x - (-8) = -5 \)

e) The sum of three consecutive odd numbers is 87
\( x + (x + 2) + (x + 4) = 87 \)
f) The sum of two consecutive even numbers is 54
\( y + (y + 2) = 54 \)
