Sir you posted question and answer? or are providing examples of preferred format?
Answer:
204 people
Step-by-step explanation:
The manager has interviewed 50 people, which is 1/6 of 300. Just times it by 6 to get an approximate amount of people :)
-3x+13=16
Move +13 to the other side. Sign changes from +13 to -13.
-3x+13-13=16-13
-3x=16-13
-3x=3
Divide by -3 for both sides.
-3/-3x=3/-3
Cross out -3 and -3, divide by -3, then becomes 1*1*x=x
x=-1
Answer: x=-1
