Answer:
x = 5
Step-by-step explanation:
You need to find de value of x.
4x - 1 = 18
4x = 18 + 1
4x = 19
x = 19/4
x = 4,75 but, the questions says: smallest integer value, so, the smallest is the integer number more near of 4,75, which is 5.
testing:
x = 5
4*5 - 1 > 18
20 -1 > 18
19 > 18 TRUE
x = 4
4*4 - 1 > 18
16 - 1 > 18
15 > 18 FALSE
