1) 3n+1=16-2n
- add 2n to both sides
- you should now be left with 5n+1=16
(remember the 2n gets canceled out)
- subtract 1 from both sides
- you should now be left with 5n=15
- now you divide by 5 to get n by itself
- 15 divided by 5 is 3
- n=3
2) substitute n with 3 in to the original equation
- so 3n+1=16-2n now becomes 3(5)+1=16-2(3)
- you should get 10 for both so 10=10
3) according to the segment addition postualte , XR + YR = XY.
- add 10+10 which stands for the lengths of XR and YR
Answer - XY = 20

Answer:
x=36
Step-by-step explanation:
first take six away from both sides to get 3/4x=27
then divide 27 by the numerator 3 to get 9. Then multiply 9 by the denominator 4 to get 36. So 3/4 of 36=27+6=33
