Full solution

Q. Evaluate 6+4a+b36+\frac{4}{a}+\frac{b}{3} when a=4a=4 and b=3b=3.
  1. Substitute values: Substitute the given values for aa and bb into the expression.\newlineWe have a=4a = 4 and b=3b = 3, so we substitute these values into the expression 6+(4/a)+(b/3)6 + (4/a) + (b/3).
  2. Perform substitution: Perform the substitution.\newlineThe expression becomes 6+(4/4)+(3/3)6 + (4/4) + (3/3).
  3. Simplify fractions: Simplify the fractions.\newline44 divided by 44 equals 11, and 33 divided by 33 equals 11.\newlineSo, the expression simplifies to 6+1+16 + 1 + 1.
  4. Add numbers together: Add the numbers together. 6+1+16 + 1 + 1 equals 88.
