Abaseball team has a goal of hitting more than 84 home runs this season. they average 7 home runs each game and have already hit 35 home runs so far. how many more games, x, will it take the baseball team to reach its home run hitting goal if they continue to average 7 home runs per game?

The equation is 7x + 35 > 84. Solving for x, you get x = 7. This is your solution

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
