18 + x > 40
a. x > 58
b. x > 22
c. x > -58
d. x > -22

The answer is: [B]: x > 22 .

Explanation:

Given the inequality:

→ 18 + x > 40 ;  

→ We want to solve, or simplify, for "x". We do this by subtracting "18" from EACH SIDE of the inequality; to isolate "x" on one side of the inequality; and solve, or simply the problem; or, value for "x".

→ 18 + x > 40 ;  

→ 18 + x − 18 > 40 − 18 ;  to get:

→ x > 22  ; → which is: 'Answer choice: [B]'.
