** (guaranteed brainliest for correct answer! ) william says that 15 years from now, his age will be 3 times his age 5 years ago. if x represents william’s present age, complete the following sentences. the equation representing william's age is william's present age is options for part a: x - 15 = 3 (x - 5) x + 15 = 3 (x - 5) options for part b: 15 years. 18 years.

Lets say that Williams current age is x, since it is currently unknown
From here we know that in 15 years (x+15) he will be 3 times his age 5 years prior (3x-5). Thus we can set these equations up as equal to one another
1) x + 15 = 3(x - 5)
2) x + 15 = 3x-15
3) 30= 2x
4) 15 = x
5) Now this age is his current age of 15 years, but they also want his age 15 years from now
The equation is x + 15 = 3(x - 5)

This should be correct now, sorry for the misconception. Good luck
