Complete the process of solving the equation.Fill in all missing terms and select all missing descriptions. Simplify any fractio

Bumek [7]

The second description is not suitable.

It should be "simplify the terms" sice you are just adding 36 and -20.

Consider the given expression,

$3\mleft(9u+12\mright)-16=20$

Apply the distributive property,

$\begin{gathered} 3(9u)+3(12)-16=20 \\ 27u+36-16=20 \end{gathered}$

Combine like terms,

$27u+20=20$

Subtract 20 from both sides,

$27u=0$

Divide both sides by 27,

$u=0$
