Question

ecuaciones de primer grado.
obtenga el valor de x
3(x + 1) + 2(x + 3)= 5(x + 1) + 2(x + 2)​

Answer 1

Respuesta:

x = 0

Explicación paso a paso:

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

3x + 3 + 2x + 6 = 5x + 5 + 2x + 4

5x + 9 = 7x + 9 => x = 0

Comprobación:

3(0 + 1) + 2(0 + 3)= 5(0 + 1) + 2(0 + 2)

3(1) + 2(3)= 5(1) + 2(2) => 3 + 6 = 5 + 4 => 9 = 9

RPTA: x = 0
