Question

Calcular el valor de x y verificar el resultado. "x-(2-x)+3=5-(1-x)

Answer 1

x - (2 - x) + 3 = 5 - (1 - x)

x - 2 + x + 3 = 5 - 1 + x

x + x - 2 + 3 = 5 - 1 + x

2x + 1 = 4 + x

2x - x = 4 - 1

x = 3

Solución : 

x = 3

COMPROBAMOS : 

x - (2 - x) + 3 = 5 - (1 - x)

3 - (2 - 3) + 3 = 5 - (1 - 3)

3 - 2 + 3 + 3 = 5 - 1 + 3

7 = 7

La solución es correcta. 

Answer 2

x-(2-x)+3=5-(1-x)
x+2+x+3=5+1+x
x+x+x=-2-3+5+1
+3x=+5
x=+5/3
x =5/3
