The second place to the right after the decimal is the hundredth, so basically, to round, you cut off the rest of the decimal places afterwards. If the number after the hundredth is at or above 5, you should make the hundredth 1 higher, but if it is 4 or below, you will just leave it as is. In this case, 3.047 rounds to 3.05. There really is not any math work to show, but just the explanation.<span />

Answer:
infinite solutions
Step-by-step explanation:
replace x with 3y + 9 in the second equation

this means whatever numver you write instead of y there will be a solution.
