Answer 2

let maria be of x years
steven be of y years
x+12=2y
(x+12)/2=y
x+y=36
y=36-x
y=(x+12)/2
36-x=(x+12)/2
2(36-x)=x+12
72-2x= x+12
60=3x
60/3=x
20=x
x+y=36
20+y=36
y=16
current ages ; maria :20 steven:16

Answer 5

Problem Correct Answer Your Answer
1 12 years from now Maria will be twice as old as Steven.
The current sum of the ages of Maria and Steven is 36.
How old is Steven right now?
Solution
Maria + 12 = 2 × (Steven + 12)
Maria + Steven = 36
Maria = 36 - Steven
36 - Steven + 12 = 2 × (Steven + 12)
48 - Steven = 2 × Steven + 24
48 = 3 × Steven + 24
3 × Steven = 48 - 24 = 24
Steven = 8

Answer 14

x+12=2(y+12)
x+y=36
x+12=2y+24
x+12-24=2y
x-12=2y
(x-12)/2=y
x+y=36
x+(x-12)/2=36
(2x+x-12)/2=36
3x-12=72
3x=84
x=28
y=(28-12)/2=16/2=8 years

this means let maria's age be x and steven's age be y
