Question

Rezolvati ecuatia in multimea N efectuand si verifificarea;
x+18=24, x:12=96 , a+35=20 ,t:6=100 ,8z=160 ,9x-1=0 ,5y=18 ,4x-20=0

Answer 1

x+18=24
x=6
V : 6+18 = 24
 x:12=96
x=1152
V: 1152:12=96
a+35=20 Acesta este gresit , nu are cum sa aduni x cu un numar mai mare si sa dea unul mai mic
t:6=100
t=600
V:600:6=100
8z=160
z=20
8x20=160
9x-1=0
x=0
V: 0-1 = 0
5y=18
y=3,6 V: 3,6x5 = 18
4x-20=0
4x=20 => x=5 V: 4x5-20=0

Answer 2

x=24-18

x=6

x=96*12

x=1152

a=35-20

x=15

t=100*6

t=600

z=160impartit 8

z=20

y=18impartit5

y=3,6

4x=20

x=20impartit 4

x=5
