5+3(5-✘)=17

To find the value of the expression 5+3(5-✘), we need to follow the order of operations, which is parentheses first, then multiplication or division, and finally addition or subtraction. Here's the step-by-step solution: 1. Start with the expression 5+3(5-✘). 2. Simplify the expression inside the parentheses: 5-✘ (We don't know the value of ✘, so we leave it as is). 3. Multiply 3 by the result from step 2: 3(5-✘). 4. Distribute the 3: 3(5) - 3(✘). 5. Solve the multiplication: 15 - 3(✘). 6. Now, we are left with 15 - 3 times something (represented as ✘). Since we don't know the value of ✘, we cannot simplify it further. 7. Finally, add 5 to the result from step 6: 15 - 3(✘) + 5. Therefore, the expression 5+3(5-✘) cannot be further simplified or calculated to be equal to 17 without knowing the value of ✘.
