Question

[12-9:3+(12-9): 3] *z +1=41


33:(r+19)= 80:2:5:4:2


{[( v+4)*6} :4= 15 


Va rog frumos cine ma ajuta???!!!

Answer 1

[12-9:3+(12-9): 3] *z +1=41
[12-3+3: 3] *z +1=41
[12-3+1] *z=41-1
10 *z=40
z=40:10=4

33:(r+19)= 80:2:5:4:2
33:(r+19)= 1
r+19=33
r=33-19=14

{[( v+4)*6} :4= 15 
{[( v+4)*6} = 15 x4
6v+24=60
6v=60-24
6v=36
v=36:6
v=6
