b) 2(5x-4)=7(2x-3)
c) 25 (x+23 ) + 6= 32( X-2) +11
d) (2x-3) (3x+4) = (x+7)(6x-8) +3

Va rog frumos​

Answer 1

Răspuns:

a)5x-3x=-2-7

2x=-9

x=-9\2

b)2•5x-2•4=7•2x-7•3

10x-8=14x-21

10x-14x=-21+8

-4x=-13

x=-13/4

Explicație pas cu pas:

c)25x+275+6=32x-64+11

25x+581=32x-53

25x-32x=-53-581

-7x=-634

x=634/-7
