Answer 1

yeah very grt question....
it's on our eyes...but we don't pay much attention
Linear equations use one or more variables where one variable is dependent on the other. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph.
and many more

Answer 2

Answer:

Step 1: Simplify each side, if needed.

Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.

Step 3: Use Mult./Div. ...

Step 4: Check your answer.

I find this is the quickest and easiest way to approach linear equations.

Example 6: Solve for the variable.
