9x–42=5 is x = 11.
<u>Step-by-step explanation:</u>
9x- 42 = 5...
When we put x = 9
then we will get 81 - 42 =39
put x = 10 then
9(10) - 42 = 90 - 42 - 48
put x = 11
then 9(11) - 42 = 99-42 = 57
So x = 11 is the answer.
Hey there!
PEMDAS simply means (the OVERALL question answer)
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
Here’s an example
24 - 4^2 + 2 * 4
= 24 - 16 + 2 * 4
= 24 - 16 + 8
= 8 + 8
= 16
Thus, the answer for that equation is: 16
Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)
• Please
• Excuse
• My
• Dear
• Aunt
• Sally
Good luck on your assignment & enjoy your day!

Answer:
x = 8
Step-by-step explanation:
Corresponding segments are proportional.
(3x +1)/10 = (7x -1)/22
11(3x +1) = 5(7x -1) . . . . . . multiply by 110
33x + 11 = 35x -5 . . . . . . eliminate parentheses
16 = 2x . . . . . . . . . . . add 5-33x to both sides
8 = x . . . . . . . . . . divide by 2
