It would be 14 for the perimeter
X-y=2 (*-2) --> -2x+2y=-4
2x+3y=14
------------------
2x+3y=14
-2x+2y=-4
------------------
5y=10
y=2
Answer:age of the man: 75 age of the woman:25
Step-by-step explanation:
First, We need to define the variables
x: age of the man
y: age of the woman
at the first time he has three times her age
x=3y (1)
in 25 years time
(x+25)=2(y+25) (2)
we clear the equation
X+25=2y+50
X=2y+25
we substitute in the (1) equation:
2y+25=3y
y=25
x=3*25=75
