you bought a magazine for $5 and four erasers. you spent a total of $25.

Magazine cost: 5$ each
Eraser cost: X$ each


Not exactly but hope it helps to solve

Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.

1(5) + 4(X) = 25

5 + 4X = 25

subtract 5 from both sides

4X = 25 - 5

4X = 20

divide both sides by 4

X = 20/4

X = 5

Each eraser cost 5$
