Work out the following. 33 + 8 x 9 =
(31 - 20) x 3 =
102 - 6 = (8-5) =
120 = (12 + 4 x 7) - 2 =​

8 × 9 = 72

33 + 72 = 105

The answer is 105

31 - 20 = 11

11 × 3 = 33

The answer is 33

102 - 6 = 8 - 5

102 - 6 = 96

96 = 8 - 5

8 - 5 = 3

96 = 3

93 = 3 is false so therefor, this equation has no solution.

4th Equation:

102 = 12 + 4 × 7 - 2

4 × 7 = 28

102 = 12 + 28 - 2

12 + 28 = 40

102 = 40 - 2

40 - 2 = 38

102 = 38

102 = 38 is false so, it means that this equation has no solution.
