After distributing, you will have several $x$ terms and constant terms. Group all $x$ terms together and all constant numbers together on each side.

Once the equation is simplified, get all the $x$ terms on one side of the equation (for example, by subtracting an $x$ term from both sides).

When you have an equation that looks like $x - 5 = 3$ or something similar, what operation do you do on both sides to get $x$ alone?

In Desmos, type y = 8x - 5 on one line and y = 3(2x + 1) + x on another line to graph both sides of the equation as separate lines.

Look for the point where the two lines intersect and tap/click it; the x-coordinate of this intersection is the value of $x$ that satisfies the equation.

You can also type 8x - 5 - (3(2x + 1) + x) and use the table feature; the value of $x$ that makes this expression equal to 0 is the solution to the equation.

Start with the equation:

Distribute the $3$ across the parentheses on the right:

So the equation becomes:

Now combine the $x$ terms on the right side:

So the equation simplifies to:

Subtract $7x$ from both sides so that all $x$ terms are on the left:

which simplifies to:

Now isolate $x$ by adding $5$ to both sides:

which gives:

So the value of $x$ is $8$.
