x=4

Step-by-step explanation:

Distrubutive property: 5x-50=30-15x

get x on one side: 5x-50+15x=30

combine like terms: 20x-50=30

subtract on both sides: 20x=30+50

20x=80

simplify: 20/20=80/20

x=4

5x - 50 = 30 - 15x
30+50= 80
-15x - 5x = -20x

-20x = 80

DanielleElmas [232]

Answer: Yes, we have.

Step-by-step explanation:

Going by the details provided, Probability of success of choosing a citizen with a fitness band 27%
