Answer:
11x+4+5=180 ok first we have to put all the naked numbers on one side and the x's number on one side, and by doing that a easier way to do that is you switch the spots but their symbols - and + change so if its negative - its going to turn into a + positive and + to a -
11x = 180 - 5 - 4
11x = 171 and since theres mutliplication 11 times x which is 11x, were going to divide
x = 171/11 and the out come is with decimals (15.54545...etc)
x=11 is incorrect

Answer:
20 questions
Step-by-step explanation:
Given




Required
Number of questions answered
First, we need to get the total correct marks obtained by Roy
This is calculated by multiplying the correct marks by number of correct answers


Subtract this from the total scores obtained; This gives the total incorrect answer obtained by Roy


Open bracket


Divide this by -2 to get the number of incorrect answers


Add this to the number of correct answers to give the total number of question answered



<em>Hence, Roy answered a total of 20 questions</em>
The order to us solve is:
- Parentheses
- Multiplication
- Sum and subtraction
Let's go:

Therefore, the result is 62.2.
