Question

The math problem says to add the numbers A and B. But, by mistake , you subtract B from A and get 66. However 66 is 1/3 of correct answer

Answer 1

. I should find the result (R) of add A y B.

A + B = R

- But, I got:

  B - A = 66

→ B = 66 + A (1)

- However,  66 is 1/3 of the correct answer , so

A + B = 66 x 3

→ A + B = 198 (2)

- If eq. (1) is replaced in eq.(2), it got:

→ A + A+ 66 = 198 → 2A + 66 = 198

→ 2A = 198 - 66

→  2A = 132

→ A = 132/ 2

→ A= 66

and B, is.

B = 66 + 66

→ B = 132
