25 subtracted from the producd of a number and 7 is less than - 39

equation: 7x - 25 < - 39

solution: x < - 2

Step-by-step explanation:

let the number be x

"product of a number and 7" : 7x

"25 subtracted from the product ... " : 7x - 25

" ... is less than - 39) : 7x - 25 < - 39

solving equation

7x - 25 < - 39 (add 25 to both sides)

7x < - 39 + 25

7x < - 14 (divide both sides by 7)

x < - 14 / 7

x < - 2
