EXPLAIN

Answer 1

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

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

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$

Answer 2

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$
