Plug x=3 into the equations
Think of the sign as a mouth. The mouth eats the bigger number.
2(3)+3<10
6+3<10
9<10
9 is less than 10 so this one is true
2(3)-3<4
6-3<4
3<4
3 is less than 4 so this one is true
5+3(3)>15
5+9>15
14>15
14 is NOT greater than 15 so this one is false
12-3(3)>2
12-9>2
3>2
3 is greater than 2 so this one is true
