Question 1176545
<br>
The given information compares the numbers of medals for both Great Britain and China to the number for the US, so the problem is probably easiest to set up using x as the number of medals won by the US.<br>
x = # won by the US
x-51 = # won by China
x-54 = # won by Great Britain<br>
Use those expressions to write and solve an equation that says the total number of medals won by those three countries was 258.<br>
