Question

va rog mult cele două exerciții​

Answer 1

a) 24:[10×(x-4):5-4]-6=0

24:[10×(x-4):5-4]=0+6

24:[10×(x-4):5-4]=6

10×(x-4):5-4=24:6

10×(x-4):5-4=4

10×(x-4):5=4+4

10×(x-4):5=8

10×(x-4)=8×5

10×(x-4)=24

x-4=24-10

x-4=14

x=14+4

x=18

b) 2×{20+[60-(2×x+12):5]:10}=50

{20+[60-(2×x+12):5]:10}=50:2

20+[60-(2×x+12):5]:10=25

[60-(2×x+12):5]:10=25-20

[60-(2×x+12):5]:10=5

60-(2×x+12):5=5×10

60-(2×x+12)=50

(2×x+12)=60-50

2×x+12=10

2×x=12-10

2×x=2

x=2:2

x=1
