Despejar la variable <br> 5x+11=56

Karolina [17]

Hola!

x = 9

Explicación:

Resta 11 de ambos lados

5x + 11 - 11 = 56 - 11

Usted obtiene:

5x = 45

Divide ambos lados por 5

5x/5 = 45/5

Usted obtiene:

x = 9

English:

Subtract 11 from both sides

5x + 11 - 11 = 56 - 11

You get:

5x = 45

Divide both sides by 5

5x/5 = 45/5

You get:

x = 9
