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
4^x=2×2^x=2×7=14
4^x-1=14-1=13
(f+g)(x)=0
f (x) + g (x)=0
now,
substitute their values
x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0
we have to find it's zeroes (or roots) now:
x-6 =0
x = 6
x +3 =0
x = -3
