Question

Por favor resolver x+x/2+x/4=175000 x+x/3+x/4+x/27=120

Answer 1

x + x/2 + x/4 = 175000

4 * (x + x/2 + x/4) = 175000 * 4
4x + 2x + x = 700000
7x = 700000
x = 700000 : 7 = 100000



x + x/3 + x/4 + x/27 = 120
108 * ( x + x/3 + x/4 + x/27) = 108 * 120
108x + 36x + 27x + 4x = 12960
175x = 12960
x = 12960 : 175 = 74,06
