To solve each problem, the following calculations must be done:

1)

(54 - 12) / 2 = X

42 / 2 = X

21 = X

21 + 12 = 33

33 + 21 = 54

2)

(92 - 3) / 2 = X

89 / 2 = X

44.5 = X

44.5 + 3 = 47.5

44.5 + 47.5 = 92

3)

1000 / 3 x 2 = 666.666

0.666 x 6 = 3.999

0.333 x 6 = 1.999

4)

1/5 + 1/X = 1/2

10/5 + 10/X = 10/2

2 + X = 5

X = 5 - 2

X = 3

5)

5 /// 1

8 /// 4
