¿Cuál es la respuesta? 5+2x=5x-7

mueva la variable al lado izquierdo y cambie su signo, (5 + 2x-5x = -7)

Reúna términos semejantes (-3x = -7-5), luego divida ambos lados de la ecuación por -3

Entonces obtienes x = 4

In english:

x=4

move the variable to the left side and change its sign, (5 + 2x-5x = -7)

Collect like terms (-3x = -7-5), then divide both sides of the equation by -3

So you get x = 4
