Question

Solve inequalities using multiplication? Solve x/4<5

Answer 1

The solution for the inequality is x < 20.

_________________________________________________________

We're given the inequality
`\boldsymbol{\sf{\cfrac{x}{4} < 5}}`. And to solve the inequality, I am going to isolate x on the left side of the inequality.

And to isolate x, I'll multiply both sides by 4, like this :

⇒
`\boldsymbol{\sf{x < 5*4}}`

⇒
`\boldsymbol{\sf{x < 20}}`

∴ x < 20

Answer 2

x<20

Explanation:

Multiply both sides by 4.

x<20
