Question

Se tiene la igualdad 2(1 + 2x) = 10, el número que satisface la igualdad como tal, es:

Answer 1

Respuesta:

$2(1 + 2x) = 10\\2+4x=10\\4x=8\\x=8/4\\x=2$

Answer 2

$\mathtt{2(1 + 2x) = 10} \\ \\ \mathtt{2 + 4x = 10} \\ \\ \mathtt{4x = 10 - 2} \\ \\ \mathtt{4x = 8} \\ \\ \mathtt{ \frac{4x}{4} = \frac{8}{4} } \\ \\ \boxed{\mathtt{x = 2}}$
