Answer:
-222
Step-by-step explanation:
Solve the ones in the parentheses first.
3 × -5 = -15
23 × -9 = -207
(3 × -5) + (23 × -9)
-15 + (-207)
-15 - 207
-222
Answer:
(3x -5) + (23x -9) = 26x - 15
Step-by-step 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
