Problema de matematica. pls dau coroana​

Answer 1

Răspuns:c)4  B)6

Explicație pas cu pas:

c) 4x+2/6+x/6-3/4=35/12+x-4/2=

5x+2/6-3/4=35/12+x-4/2

=10x+4/12-9/12=35/12+6x-24/12=

=10x+4-9/12=6x-24+35/12=

=5x/12=x-15+31/12

=5x/12=x+16/12=

4x/12=16/12

4x=16

x=4

b)6x-3/60+4x+8/60-15/60=x+1+7/12

10x-3+8-15/60=x+8/12

10x-18+8/60=5x+40/60

10x-10/60=5x+40/60

10x-10=5x+40

6x-10=x+40

6x=x+30

5x=30

x=6
