Answer:
A = 2.94
Explanation:
You need to isolate the variable. This can be done by performing the same operation to each side to eliminate the unwanted term. In this case, you should divide both sides by 34. This removes the 34 from the left side while also doing the same thing to both sides of the equation.
When you divide 34 from 100, you are left with 2.94 on the right side. Because the only thing on the left side is the variable, this would be your answer.
