Question

Which value of x makes the open sentence true? 10+2x<15x−20

Answer 1

3

Step-by-step explanation:when we give a value to x we can simply see if ıt works out:

lets say x=2:

10+2.2<15.2-20= 14<10 this is wrong so this means x is not 2

lets say x=3

10+2.3<15.3-20=16<25 and this is true
