Answer 2

Respuesta:

3(8x-2)-45+4x = 4(5x+6)/2

24x-6-45+4x = 20x+24/2

(24+4)x-6-45 = 20x+24/2

28x-51 = 20x+24/2

2(28x-51) = 2(20x+24)/2

56x-102 = 20x+24

56x-20x = 24+102

36x = 126

36x/9 = 126/9

4x = 14

4x/2 = 14/2

2x = 7

2x/2 = 7/2

x = 7/2

Comprobación :

3(8(7/2)-2)-45+4(7/2) = 4(5(7/2)+6)/2

3(4(7)-2)-45+2(7) = 4(2,5(7)+6)/2

3(28-2)-45+14 = 2(2,5(7)+6)

3(26)-45+14 = 2(17,5+6)

78-45+14 = 2(23,5)

33+14 = 47

47 = 47

R// " X " vale 7/2 .
