linda and mark their ages total 80years.2years ago 2times marks age was 2 years more than 3 times lindas age how old are they? thank you
Answer provided by our tutors
Let Linda's age be x
Let Mark's age be y
x+y=80 (solve for y)
y=80-x (subitution)
Two years ago Mark's age = y-2
Two years ago Linda's age = x-2
Equation:
3(x-2)+2=2(y-2)
3x-6+2=2y-4
Subsitue for y
3x-4=2(80-x)-4
3x-4=160-2x-4
5x=160
x=32
y=80-32
y=48
Hence, Linda is 32 years old and Mark is 48 years old.
