Respuesta:
10x-2x = 9+5x+77
8x = (9+77)+5x
8x = 86+5x
8x-5x = 86+5x-5x
3x = 86
3x/3 = 86/3
x = 86/3
Comprobación :
10(86/3)-2(86/3) = 9+5(86/3)+77
(860/3)-(172/3) = (9+77)+5(86/3)
668/3 = 86+430/3 ; 86 = 258/3
668/3 = 258/3+430/3
668/3 = (258+430)/3
668/3 = 688/3
R// Por ende , x vale 86/3 en esa ecuación
Explicación paso a paso:
