Replace B and small b and A by its values then multiply by 2 on both sides. You will get 42= 7h then h=6
The answer to h = 6.

The reason is, A = 21 and the two b’s both together are equaled to 7, so we need to find the missing number to multiply 7, so when we put 6 in the h spot, it is multiplied by half, making it 3, So now we have simple multiplication of: 7 x 3 = 21. Thank you and hope this helps.
