Question 1175289: Can someone help me understand which title goes to the correct category?
Lewis is saving for a down payment of $8,750 on a house. The initial amount of money he has saved is $250, and the amount of money he plans on saving every month is $340. To model the situation, he created this equation, where x represents the number of months and y represents the total amount of savings:
y = 250 + 340x.

steps....................................justification
y+=+250+%2B+340x..................given
+y+-250=+250+-250%2B+340x......subtraction property of equality
y+-250=++340x.......................simplification
%28y+-250%29%2F340=++340x%2F340....................division property of equality
%28y+-250%29%2F340=+x .............simplification
y%2F340+-250%2F340=+x.substitution and simplification
