Ralph is 3 times as old as Sara. In 6 years, Ralph will be only twice as old as Sara will be then. Find Ralph's age now.
Which of the following equations could be used to solve the problem?
3x + 2x
x + 6 = 2(3x + 6)
3x + 6 = 2(x + 6)
3x + 6 = 2x + 6

So y = years old of Ralph
x = of years old of Sara
given: y = 3x
using the third function, or C
3x +6 = 2(x +6)
3x = 2x +6
x = 6
y = 3 (6)
y = 18
6 years later:
x = 6 +6 = 12
y = 18 + 6 = 24
x+6 = 2x = y+6
So the answer is C
or the third one, I will say
It could also work if sarah was 3 and Ralph was 12
oops not 3, 4
NM this entire equation for me is a train wreak :/ sorry lol! just go with the other guys
