Answer:

36 years old

Step-by-step explanation:

let x = age of Rachael

2x+3 = current ages combined

[(2x+3)+4]+4 = 75

2x+11 = 75

2x = 75-11

2x = 64

x = 32

Rachel is 32 years old. Isaac is 3 years older, which is 35 years old.

Hope this helped! If you need any help, tell me in the comments.

I hope this clears it up. R is Rachaels age and I is Isaacs age. The first equation at the top represents that Isaac is 3 years older than Rachael. The second equation represents their combined ages in 4 years. Follow the arrows to see where I get my numbers and variables
