Answer 3

let's say we pick a random number 15.1 from the set

replace x with 15.1 to see if x+4 = 8.4 is true


x+4 = 8.4
15.1+4 = 8.4
19.1 = 8.4

since 19.1 = 8.4 is false, this means x = 15.1 is NOT the solution to x + 4 = 8.4

Answer 4

you are looking for values that make x + 4 = 8.4 true

Answer 5
