Answer 1

$\boxed{\fcolorbox{green}{beige}{Answer}}$

The value of a is 4 and the value of b is 7.

$\boxed{\fcolorbox{green}{red}{Step-by-step explanation:}}$

$\small\blue{★}$Consider the provided information.

It is given tat $\boxed{\fcolorbox{red}{blue}{2ab + ab1 = b18}}$

$\red{★}$Now place the digits according to their place value.

  2 a b

+ a b 1

  b 1 8

$\green{★}$Consider the digit at once place:

$\boxed{\fcolorbox{green}{pink}{b + 1 = 8 ⇒ b = 7}}$

Now substitute b = $\boxed{\fcolorbox{green}{beige}{7 in a + b = 11}}$

$\boxed{\fcolorbox{green}{orange}{a + 7 = 11 ⇒ a = 4}}$

Hence, the value of a is 4 and the value of b is 7.
