Question 387557: I really need HELP! Week 4 Application Assignment Answer the following questions. In 2004 Major League Baseball, Barry Bonds, playing for the San Francisco Giants of the National League, collected 44 hits in 117 at-bats in his first 49 games. The ratio of number of hits to number of at-bats, rounded to the nearest thousandth, is a player’s batting average. What was Bond’s batting average in his first 49 games? Set the ratio hits to at-bats and convert to a decimal. Based on the ratio of number of hits to number of games, how many hits would he get in a 162-game season? Set a proportion and solve for the unknown. Based on the ratio of number of hits to number of at-bats and assuming he bats 400 times in 2004, how many hits would he get?

Question 387643: PLEASE HELP! THANK YOU.
Solve my substitution method.
6x+5 = 5 and
x = 30 - 5y. I know that in the second equation x is already solved for so I would substitute this into equation one right?
6(30 - 5y) + 5 = 5; 180 - 30y +5 = 5;
NOT SURE AFTER THIS.
