Answer is x=151 and x=200
Step by step
The greater than sign > means the number to the left of the sign is “greater than” , bigger, more than the number to the right.
One way of remembering which sign to use is to look at the sign as a mouth eating the bigger number. Example of our correct answers.
✅151 > 150 it’s eating the bigger number
✅200 > 150 it’s eating the bigger number
The less than sign < can be used with our incorrect answer 16
❌ 16 < 150
See, 16 is less than 150 and it is eating the bigger number.
I hope this helps
