Question

rezolvati ecuatii:
a)8x-3=941;
b)17+4a=1025;
c)(21-z:21=0;
d)44:(C+44)=1;

Answer 1

a)8x-3=941=>8x=941+3=>8x=944=>x=944:8=>x=118
b)17+4a=1025=>4a=1025-17=>4a=1008=>a=1008:4=>a=252

Answer 2

a)8x-3=941 /+3
8x=944 /:8
x=118

b)17+4a=1025 /-17
4a=1008/:4
a=242


c) (21-z):21=0/•21
21-z=0/+21
-z=21/•(-1)
z=-21

d)44:(c+44)=1/•44
c+44=44/-44
c=0
