Question

3(x+2)=x-5 quanto é?​

Answer 1

Oi...

3(x + 2) = x - 5

3x + 6 = x - 5

3x - x = - 5 - 6

2x = - 11

x = - 11/2

a)

x/3 + x/2 = 5/2⇒mmc = 6

2x + 3x = 15

5x = 15

x = 15/5

x = 3

Bons estudos.

Answer 2

Resposta:

3(x+2)=x-5

3x+6=x-5

3x-x=-5-6

2x=-11

x=-11/2=-5,5

X/3+x/2=5/2

2x/6+12x/6=15/6

2x+12x=15

14x=15

X=15/14
