Answer:
Answer is the 2nd one.
Step-by-step explanation:
254
x-39=215
215+39=x
215+39=254
70
40 is 20% of x
40 = .2 * x
40/.2 = x
x =200
x is 80% of y
x = .8 * y
200 = .8 *y
200/.8 = y
250 =y
x+y
200+250
450
The best first step to solve this is to just subtract 5/3 from both sides so it is easier to simplify.
