To check a solved equation, you can substitute the values back into the original equation and verify if both sides are equal.

Let’s look at the equations you’ve provided:

1. 1,375 × 2 = 2,750
2. 1,375 × 3 = 4,125
3. 1,375 × 2 + 3 = 2,753
4. 1,375 × 3 + 2 = 4,127

For checking:

– For 1,375 × 2 + 3, calculate:

( 1,375 × 2 = 2,750 )

Then add 3:

( 2,750 + 3 = 2,753 )

– For 1,375 × 3 + 2, calculate:

( 1,375 × 3 = 4,125 )

Then add 2:

( 4,125 + 2 = 4,127 )

In summary, to check that an equation is correct, follow the order of operations and confirm that the calculations are accurate. Keep practicing, and if you need further assistance, consider checking the extended services page!
