Question

Four more than 3 times a number is at least 22

Answer 1

let the number = x

3 times a number(x) = 3x

Four more than 3 times a number is at least 22​ can be expressed below

`3x\text{ + 4 }\ge\text{ 22}`

At least 22 simply means the lowest number is 22 or greater than 22. This means 3x + 4 is equals to 22 or greater than 22.
