Răspuns :

Răspuns:

a) 3x = 15 => x = 5

b) - x = 4 => x = -4

c) 2x = 12 => x = 6

e) 3x = 15 => x = 5

f) x = 4

g) x = -8

Răspuns:

a)3x+1=16

3x=15 => x=5

b)-x+13=18

-x=5 => x=-5

c)3x+1=x+11

2x=10 => x=5

e)9x-13=6x+2

3x=15 => x=5

f)4(x+3)=3x+16

4x+12=3x+16

=>x=4

g)6+2(x-1)=x-1

6+2x-2=x-1

2x+4=x-1

=>x=-5

Sper ca te am ajutat!
