Question

Solve Cryptarithms.
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{A}\ \ \ \text{B} \ \ \ \ 7\ \ \ \ \ \ \ \\ \ \ \ \ \ \ \ \ \ \ \underline{+\ \ \ \ 6\ \ \ \ \text{A}\ \ \ \ \text{B}\ }\\\ \ \ \ \ {\ \ \ \ \ \ \ \ \ \ \ \ 9\ \ \ \ 8\ \ \ \ \ \text{A}}$

Answer

If $\text{A}+\text{B}=8,\text{A}+\text{B}\geq9$ is possible only if A = b = 9 But from 7 + B = A, A = B = 9 is impossible. Surely, $\text{A}+\text{B}=8, \text{A}+\text{B}\leq9$
So, A + 7 = 9, Surely A = 27 + B = A, 7 + B = 2, B = 5
So, A = 2, B = 5
