"9 subtracted from a number is 40"

• n + 15 = -7

• n - 9 = 40

• 9 - n = 40

• n / 9 = 40

"-3 equals the quotient of a number and 54"

• -3 = n / 54

• -3 = n - 54

• -3 = 54 / n

• -3 = n + 54

"the total of a number and 15 is -7"

• n + 15 = -7

• n - 15 = -7

• n + (-7) = 15

• n = 15 + (-7)

"-40 is the product of a number and -4"

• -40 x n + (-4)

• -40 = n (-4)

• -40 = -4 + n

• -40 = (-4)

"a number divided by 8 is -9"

• 8 / n = -9

• n - 8 = 9

• n / 8 = -9

• n + 8 - 9

"the difference of a number and -2 is -15"

• n = 15 - 2

• n - (-15) = -2

• n - 15 = -2

• n - (-2) = -15
