Anyone can, if they know how to do it.
A linear equation describes a straight line.
Its equation contains an equals sign; + and - signs; positive and negative numbers; and a term having x in it, but not x squared or cubed or to any higher power.
So one could look like this: 5x - 3 = 7x - 12, and by using the rule "add the same to both sides or subtract the same from each side the equation can be rewritten as :
(5x -5x) + -3 +12 = 7x - 5x + (-12 +12 ), turning the ones in the brackets to zero, giving 9 = 2x
So 2x = 9 which means that x = 9/2 = 4.5

Where the given equations are not linear?
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
How are linear equations and functions alike?
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
How are functions and linear equations similar?
Linear equations are a small minority of functions.
How are functions like linear equations?
Most functions are not like linear equations.
Do linear equations contain x squared?
No, linear equations don't have x2. Equation with x and y are usually linear equations. Equations with either x2 or y2 (but never both) are usually quadratic equations.
