Answer:

4

Step-by-step explanation:

All you need to do is plug in each value for x & then solve the equation to see if it equals 7.  When a number, like 2, is next to an x you multiply the two of them.  So when you substitute a number for x, you multiply it by the 2.

2(3)-1= 5

2(4)-1= 7

2(5)-1=9
