Question

ex 1 rezolvatii urmatoarele ecuatii 
5 (3x-2)-6(8x-13)-13x=16(8-3x)-62
ex 2 revolvatii ecuatiile in multimea numerelor reale 
5x+9+3(2x-1)=2x+24

Answer 1

15x -10 -48x +78-13x= 128- 48x -62

46x+68= -48x+ 66

46x+48x=66-68

94x= -2

x= - 1/47

5x+9+6x-3=2x+24
11x+6=2x+24

11x-2x=24-6

9x=18

x=18/9=2

Answer 2

1.6x-10-48x-78-3x=128-48x--62; --3x+48x=-62+128+10+78: -45x=154 x=154supra-45    
2.5x+9+6x=3=2x+24; 11x-2x=24-9; 9x=15 x = 15 supra 9
