i got 17-20x but i don't think that is correct
7-4x+2(5x+8)
7 - 4x + 10x + 16
23 + 6x
To simplify the expression 7-4x+2(5x+8), we can follow the order of operations (PEMDAS/BODMAS) which states that we should solve operations inside parentheses, then do any multiplication or division from left to right, and finally, do any addition or subtraction from left to right.
Step 1: Simplify the expression inside the parentheses (5x + 8):
5x + 8
Step 2: Distribute the 2 across the terms inside the parentheses:
2 * 5x + 2 * 8
10x + 16
Now we have the simplified expression: 7 - 4x + 10x + 16.
Step 3: Combine like terms by combining the x terms and the constant terms separately:
(-4x + 10x) + (7 + 16)
6x + 23
The simplified expression is 6x + 23.
