Question

solve 15 + x < -45

Answer 1

Hello, I can help you with this equation. :)

Answer 2

Well, first off this means 15 + x is less than -45

Answer 3

Divide 15 from both sides, giving you -45 divided by 15. So x=-3.

Answer 4

add -15 to both sides, like this
-15+15 + x < -15+ -45

(you can always add the same thing to both sides)
now simplify both sides. what is -15+15?
what is -15+ -45 ?
