Question

How do you solve the inequality `3x>=15`?

Answer 1

See a solution process below:

Explanation:

Divide each side of the inequality by `color(red)(3)` to solve for `x` while keeping the equation balanced:

`(3x)/color(red)(3) >= 15/color(red)(3)`

`(color(red)(cancel(color(black)(3)))x)/cancel(color(red)(3)) >= 5`

`x >= 5`
