Question

Rezolvati ecuatiile:
a) x+2,5=9,16;
b) x+3,26=7,8;
c)x-3,6=2,8;
d) x-13,4=10,6;
e) x-3,2=12,61;
f) x-17,51=7,8;

Answer 1

a) x+2.5=9.16/-2.5
x= 6.66
b) x+3.26=7.8/-3.26
x= 4.54
c) x-3.6=2.8/+3.6
x= 6.4
d) x-13.4=10.6/+13.4
x= 24
e) x-3.2=12.61/+3.2
x= 15.81
f) x-17.51=7.8/+17.51
x=25.31

Answer 2

a) x=9,16-2,5
    x=6,66
b) x=7,8-3,26
    x=4,54

c) x=2,8+3,6
    x=6,4 
d) x=10,6+13,4
    x=24
e) x=12,61+3,2
    x= 15,81
