Question

3 + 3b − 1 = b + 2 + 2b

Answer 1

Respuesta:

$\boxed{\boxed{\boxed{\blue{\mathsf{\boldsymbol{ecuaciones}}}}}}$

$3 + 3b - 1 = b + 2 + 2b \\ 3 - 2 - 1 = 3b - b + 2b \\ 0 = 4b \\ \frac{ 0 }{4} = b \\\Longrightarrow\mathbf{0 = b}$

$\large\boxed{\bold{Comprobación}}$

• Sustituimos factores b = 0

3 + 3b - 1 = b + 2 + 2b

v

3 + 0 - 1 = 0 + 2 + 0

2 = 2

⟹$\large\boxed{\red{b=0}}$
