Question

DAU COROANA !!!!!!!!!!!!!!!!!!!!!!

a).x-1/2 x 5/4=1/12
b). 2 intregi 4/5+2 intregi 1/4 ori x = 3 intregi 2/5
d). 1 intreg 4/7 ori x+2 intregi 1/2=x-1 intreg 3/14

Answer 1

a).x-1/2 x 5/4=1/12
x-5/8=1/12
96x=8+60
96x=68
x=96/68
x=24/17

b). 2 intregi 4/5+2 intregi 1/4 ori x = 3 intregi 2/5
14/5+4/5+9x/4=17/5
8x/4=17/5-18/5
8x/4= -1/5
40x= -4
x= -1/10

d). 1 intreg 4/7 ori x+2 intregi 1/2=x-1 intreg 3/14
11 x/7  +5/2= x- 17/14
22x+35=14x-17
22x-14x= -35-17
 8x= -52
x= -52/8
x= -13/2
