    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
