How to find simplified form of x=-y-3z-14

just what do you mean by simplified?

There are no factors to extract, no variable appears more than once...

Standard Form: x + y + 3z = -14.

To find the simplified form of the equation x = -y - 3z - 14, we need to rearrange the equation in a way that isolates the variable x on one side.

Step 1: Combine Like Terms
Combine the terms with variables on the right side of the equation. In this case, we have -y - 3z - 14.

Step 2: Move Terms
To move the terms to the left side of the equation, we need to perform the inverse operation of what is currently being done to each term. In this case, since the terms are being subtracted, we will add them to the left side. Remember that when you change the sign of a term while moving it to the other side of the equation, the operation changes as well.

Adding -y to both sides: x + y = -3z - 14

Step 3: Simplify and Rearrange
Now that x is isolated on the left side, we have the equation x + y = -3z - 14 in simplified form.
