Question

please tell me how to solve this as I want to do this immediately ​

Answer 1

Answer:

a = 4 , b = 7

Step-by-step explanation:

ok start from the right side

think of the number you need to add to 1 to get 8

b is 7 because 7 + 1 =8

moving on to the middle column, a + b = 1

we know b=7

a + 7 gives units place 1

whic shows a = 4

in the leftmost column,

we have 1 carryover

1 + 2 + a = b

3 + 4 = 7

thish shows value of a  and b are correct
