Question

5. Write an equation using “” and then solve the equation.

On the New Year Eve, there were 7,580 tons of cargo loaded in the morning. In the afternoon, there were tons of cargos. The total weight of cargos loaded on the day weighed 12,997 tons.

Answer 1

Let's represent the unknown amount of cargo loaded in the afternoon as "x" tons.

The equation representing the total weight of cargos loaded on the day can be written as:

7,580 + x = 12,997

To solve for "x," we can isolate it by subtracting 7,580 from both sides of the equation:

x = 12,997 - 7,580

Simplifying the right side:

x = 5,417

Therefore, the amount of cargo loaded in the afternoon was 5,417 tons.
