Question

va rog ,e urgent !! dau coroana​

Answer 1

Explicație pas cu pas:

23-x = 3x 6

23-x=18. X=23-18=5

3x-9=60:5

3x-9=12

3x=21. X=21:3

X=7

23-5x=2x9

23-5x=18

5x=23-18

X=1

3x-5=22

3x=22+5

3x=27

X=27:3

X=9

Answer 2

Răspuns:

b) (23-x):6=3

23-x=3*6

23-x=18

==> x=5

c) 5*(3*x-9)=60

3*x-9=60:5

3*x-9=12

3*x=21

==> x=7

d) (23-5*x):9=2

23-5*x=18

5*x=5

==> x=1

*e) 24:(5-x)=6

5-x=144

==> x=139

*f) 32:(13-5*x)=4

13-5*x=128

5*x=115

==> x=23

g) 3*x-15:3=19+3

3*x-5=22

3*x=26

==> x=8
