Question

(3× -5) + (23× -9) = ?

Answer 1

-222

Explanation:

Solve the ones in the parentheses first.

3 × -5 = -15

23 × -9 = -207

(3 × -5) + (23 × -9)

-15 + (-207)

-15 - 207

-222

Answer 2

(3x -5) + (23x -9) = 26x - 15

Explanation:

(3x - 5) + (23x - 9)

First, we will start by opening the bracket

3x - 5 + 23x -9

The next thing to do is to re-arrange the equation

3x + 23x -9 -5

Then next is to add the x variables separately and the constant separately

26x - 15

We will now check if we can factorize

Taking a look at it, it cannot be factorize, so we will leave it the way it is, that will be our final answer.

Therefore (3x -5) + (23x -9) = 26x - 15
