Q. What value of qq is a solution to this equation?\newline7q=777q = 77\newlineChoices:\newline(A)q=9q = 9\newline(B)q=11q = 11
  1. Identify Operation: Step 11: Identify the operation and set up the equation.\newlineThe equation given is 7q=777q = 77. We need to solve for qq.
  2. Isolate q: Step 22: Isolate q by dividing both sides of the equation by 77.\newline7q7=777\frac{7q}{7} = \frac{77}{7}\newlineq=11q = 11
  3. Check Solution: Step 33: Check the solution by substituting qq back into the original equation.7×11=777 \times 11 = 77This confirms our solution is correct.
