Joe has 32 less than 3 times as many shirts as Mark. Together, Joe and Mark have 108 shirts. How many shirts does Joe have?
Answers
Answer:
mark has 35 shirts
and joe has 73
let mark have x shirts and
joe have y shirts
therefore,by the given condition
joe will have shirts 3x-32
therefore, y=3x-32
thus 3x-y=32..................(1)
from second condition,
x+y=108...........................(2)
now adding equation (1)and(2)
3x-y=32
+
x+y=108
we get,4x=140
therefore x=140/4
x=35
put value of x in equation (2)
x+y=108
35+y=108
y=108-35
therefore, y=73
thus mark has 35 shirts and
joe has 73 shirts
x+y=108
x-3y=-32
solve it by subtracting eq1 with 2
you'll get y=35 and x=73
and here x and y are number of shirts of joe and mark respectively
And if you will still face any doubt in the answer confirm it by putting the values of x and y in any of the eq
if I'll put it in eq where x+y=108
so 73+35=108
that is 108=108
LHS=RHS
