Certainly! To find the expression Jamal wrote by doubling the coefficient but keeping the constant the same, we follow these steps:
1. Initially, Jamal wrote the expression 3 + 5a.
2. To double the coefficient (the number in front of 'a'), we multiply it by 2. In this case, the original coefficient is 5, so doubling it gives us 2 * 5 = 10.
3. By keeping the constant (the number without a variable) the same, which is 3 in this case, the new expression Jamal wrote would be 3 + 10a.
Therefore, the other expression Jamal wrote by doubling the coefficient but using the same constant is 3 + 10a.
