user100 [1]

Answer:

\Large\boxed{\mathsf{\Rightarrow NO\quad SOLUTIONS}}

Step-by-step explanation:

<h3><u>TO SOLVE:</u></h3>

Isolate by the x on one side of the equation.

<h3><u>SOLUTIONS:</u></h3>

First, subtract 3x from both sides.

\displaystyle \Rightarrow \mathsf{3x+11-3x=3x-11-3x}}

Solve.

\displaystyle \mathsf{11=-11}

Sides are NOT equal.

\Large\boxed{\mathsf{\Rightarrow THERE \quad ARE \quad NO \quad SOLUTIONS}}}

Therefore, there are no solutions.
