Question

cuanto es 2.x+1=4.2+x-3

Answer 1

Respuesta:

2(x+1) = 4(2+x)-3

2x+2 = 8+4x-3

2x+2 = 4x+(8-3)

2x+2 = 4x+5

2-5 = 4x-2x

-3 = 2x

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

-3/2 = 2/2x

-3/2 = x

x = -3/2

Comprobación :

2((-3/2)+1) = 4(2+(-3/2))-3

2((-3/2)+(2/2)) = 4((4/2)+(-3/2))-3

2((-3+2)/2) = 4((4-3)/2)-3

2(-1/2) = 4(1/2)-3

-2/2 = (4/2)-3

-2/2 = 2-3

- 1 = - 1

R// " X " vale - 3/2

Answer 2

Respuesta:

x = 4

Explicación paso a paso:

2.x + 1 = 4.2 + x - 3

2x + 1 = 8 + x - 3

2x + 1 = 5 + x

x = 4
