16 less than a number equals -19. what is the number?

We’ll use x to represent the mystery number.

“Sixteen less than” means subtraction, so we have 16 -

“Less than a number” simply means 16 - x

“Equals - 19” sets 16 - x equal to -19. In other words, 16 - x = -19

To solve, we subtract 16 to get x alone:

-x = -35

Divide the entire equation by -1 to make x positive:

-1(-x = -35) leaves us with x = 35

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
