Answer:
The Answer is B 2x+8=4
Step-by-step explanation:
I checked my answer in this app called QuickMath
Let present ages of father be x and of son is y years
x/y = 7/2, 2x=7y, y=2x/7
(y+5)=37/100*(x+5)
(2x/7+5)=37/100*(x+5)
(2x+35)/7=(37x+185)/100
200x+3500=259x+1295
259x-250x=3500-1295
59x=2205
x=37.37 years
Yes if you convert it into a rational number it will be -155/10
