In the first three innings of a baseball game, the home team scored some the rest of the game, they scored 5 runs more than the number of runs scored in the first three innings. If the home team scored 9 runs in all, how many runs did they score during the first three innings? How many runs did they score in the remainder of the game?
x = score in 3 innings
x+5 = score in remaining innings summed = 9
x + x+5 = 9 solve for x the 3 inning score, then the remaining innings score is x+5
