Q. Evaluate the expression 7+4b 7+4b when b=3 b=3
  1. Substitute b value: Substitute the value of bb into the expression.\newlineWe are given that b=3b=3, so we substitute 33 for bb in the expression 7+4b7+4b.\newline7+4b7 + 4b becomes 7+4(3)7 + 4(3).
  2. Perform multiplication: Perform the multiplication in the expression.\newlineNow we multiply 44 by 33.\newline7+4(3)=7+127 + 4(3) = 7 + 12
  3. Add numbers: Add the numbers to find the final value.\newlineWe add 77 to 1212 to get the final value of the expression.\newline7+12=197 + 12 = 19
