Question

7 5 2=33 3 6 3=10
4 x 8 =33 Find x

Answer 1

Answer:

x = 13

Step-by-step explanation:

7 5 2=33

3 6 3=10

4 x 8 =33

7 5 2=33

(7-1)*(5+1) - (2 + 1)  =  6 * 6  - 3  = 36 - 3 = 33

3 6 3=10

(3-1)*(6+1) - (3 + 1)  = 2 * 7 - 4 = 14 - 4 = 10

4  x  8 = 33

(4-1 )(x + 1)  - (8 + 1) = 33

=> 3 (x + 1) - 9 = 33

=> 3(x + 1) = 42

=> x + 1= 14

=> x = 13

rule is

a b c = d

=> (a - 1) * (b + 1) - (c + 1) = d
