Q. What value of aa is a solution to this equation?\newline7a=427a = 42\newlineChoices:\newline(A) a=6a = 6\newline(B) a=8a = 8
  1. Step 11: Isolate variable aa: Step 11: 7a=427a = 42\newlineTo find aa, we need to isolate it by dividing both sides of the equation by the coefficient of aa, which is 77.\newlineCalculation: a=427a = \frac{42}{7}
  2. Step 22: Calculate value of a: Step 22: Calculate the value of a.\newline4242 divided by 77 equals 66.\newlinea=6a = 6
