Inverse Operations
What is the inverse operations of addition?
Subtraction
g + 6 = 12
g = 6
-4(2h - 3)
-8h + 12
-4(2a - 1) + 5 = 81
a = -9
1/5 = 3/s
s = 15
What is the inverse operation of division?
Multiplication
g - 4 = 22
g = 26
5(-4 + k)
-20 + 5k
-2 - 2(3w - 5) = 80
w = -12
4/12 = w/24
w = 8
Using inverse operation, what would the correct answer be for 12 x 3?
4 because the inverse of multiplication is division
12 / 3 = 4
g x 15 = 90
g = 6
-(3p - 7)
-3p + 7
2(7t + 8) = 6t - 40
t = -7
5/6 = d/24
d = 20
Using inverse operation, what would the correct answer be: 24 / 6 ?
144 because the opposite of division is multiplication;
24 x 6 = 144
g / 9 = 405
g = 3,645
8(5r + 6)
40r + 48
-5(-2d + 1) = 13 + 4d
d = 3
1/3 = 9/x
x = 27
Using inverse operation, what would the correct answer be for the equation: 422 - 200 - 12 = ?
634, the opposite of subtraction is addition;
422 + 200 + 12 = 634
g x 16 = 128
g = 8
-7(4m + 11)
-28m - 77
4(-8f + 1) = -20f - 8
f = 1
3/7 = 24/y
y = 56
