Let x and y be the no. of files of songs and pictures respectively
by 1st condition we get,
650x + 2200y = 18150
65 x+220y = 1815
13x + 44y = 363
by 2nd condition we get,
x+y = 16
now solve for x and y
and u ll get answer
Answer:
x= 1/8 or 0.125
Step-by-step explanation:
8x=1
x=1/8
Answer:
Go to
Step-by-step explanation:
Ull find the answer there
let the number be xy then
x + y = 12
y - x = 2 ( because y > x)
adding we get 2y = 14 so y = 7
and x = 12 - 7 = 5
So the number is 57.
An example should make this clear.
