Question

A+a= 2
A+b= 3
A+b×2=?

Answer 1

If A + A = 2, A + B = 3, then the value of A + B × 2 is 5.

Step-by-step explanation:

Here, A + A = 2

⇒ 2 × A = 2 [since A exists two times in the expression, we can write it as a product of 2 and itself]

⇒ A = 1 [dividing both sides by 2]

and A + B = 3

⇒ 1 + B = 3 [putting A = 1]

⇒ B = 2 [transposing 1 to the right hand side]

Now, A + B × 2

= 1 + 2 × 2

= 1 + 4 [as per BODMAS rule, we have to do multiplication first and then addition]

= 5
