Question

3(x+5)-6(x-2)=4(x+2)-5(x-4) rezolvați in Q ecuatiile​

Answer 1

3x +15 -6x +12 =4x +8 -5x +20

15+12-8-20 =4x-5x-3x+6x

-1 =2x

2x = -1

x =( -1 ):2

$x = \frac{ - 1}{2}$

x = -0,5

Answer 2

Răspuns:

3(x+5)-6(x-2)=4(x+2)-5(x-4)

3x+15-6x+12=4x+8-5x+20

27-3x=28-x

-3x+x=28-27

-2x=1

x=-1/2
