Question 1143420
Darius is 87 years younger than jack.
x = j - 87
 11 years ago, jacks age was 4 times Darius’s age.
j - 11 = 4(x-11)
j = 4x - 44 + 11
j = 4x - 33
 How old is Darius now?
in the first equation, replace j with (4x-33)
x = 4x - 33 - 87
x = 4x - 120
x - 4x = -120
-3x = -120/-3
x = 40 yrs is D's age



 X= current age of Darius. the equation should contain 87,11, & 4.
x - 11 = 4(x-11) - 87
