we interpret " multiplied by 5 the result as if the number"

to be " multiplied by 5 the result is the same as if the number"

let 'n' represent the number

(2n+8)5 = -8n+4

solving for 'n' we have n= -4.4

this type of problem will typically result in an integer answer, so it is likely that the problem statement contains additional errors

we calculate that the number is -4.4
