(7 + 5b) + 1 , if b = 3.

1 answer

To find the value of the expression (7 + 5b) + 1 when b = 3, substitute b = 3 into the expression:

(7 + 5b) + 1 = (7 + 5(3)) + 1

Simplify the expression inside parentheses:

= (7 + 15) + 1

Simplify further:

= 22 + 1

Add:

= 23

Therefore, (7 + 5b) + 1 = 23 when b = 3.
