Question

How do you solve `A+6\times 21\leq 15`?

Answer 1

See a solution process below:

Explanation:

Use the standard order of operation or PEDMAS, we can multiply the two terms on the left side of the inequality giving:

`A + 126 <= 15`

Now, subtract `color(red)(126)` from each side of the inequality to solve for `A` while keeping the inequality balanced:

`A + 126 - color(red)(126) <= 15 - color(red)(126)`

`A + 0 <= -111`

`A <= -111`
