Question

What is the value of `10m-2k` when `k=2` and `m=5`?

Answer 1

See the solution process below:

Explanation:

To solve this problem we need to substitute `color(red)(2)` for `color(red)(k)` in the expression and we need to substitute `color(blue)(5)` for `color(blue)(m)` in the expression and then evaluate the expression:

`10color(blue)(m) - 2color(red)(k)` becomes:

`(10 * color(blue)(5)) - (2 * color(red)(2)) => 50 - 4 => 46`
