Answer:

X =1/39

Step-by-step explanation:

1/2+ 6X = 5/6 - 7X Transposing terms

6X + 7X =5/6 - 1/2

13X = 5/6 - 3/6

13X = 2/6 simplifying

13X = 1/3

and transposing 13:

X =1 / (13x3) reducing

X= 1/39

Step-by-step explanation:

x+y=30 solve for x x=30-y

substitute x with 30-y and solve

11.25(30-y)+22.4y=515.9

337.5+11.15y=515.9
