Respuesta:
a) x + 53 = 71
x = 71- 53
x = 18
b) -2x + 25 = 1
-2x = 1 -25
-2x = -24
-x = -12
x = 12
c) 4( [tex]\frac{x}{3}[/tex] ) + [tex]\frac{x}{9}[/tex] = 13
[tex]\frac{4x}{3}[/tex] + [tex]\frac{x}{9}[/tex] = 13
Sacas MCM=9
[tex]\frac{12x+x}{9}[/tex] = 13
12x+x = 13*9
13x = 117
x = 9
d) x + (x+1) + (x+2) = 75
x + x + x = 75 - 1 - 2
3x = 72
x = 24
Nro intermedio = (x+1) = (24+1) = 25
Espero te sirva :"D
