<h2>Linear system</h2>It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
<h3>Simplification</h3>Simplification is to make something easier to do or understand and to make something less complicated.
Given
The expression is .
The equivalent equation.
<h3>How to find the equivalent equation.</h3>The expression is .
On simplifying. we get
The equivalent equation is x - 4 = 0.
More about the linear system link is given below.
For this case we must resolve the following inequality:
Adding 7 to both sides of the inequality:
Different signs are subtracted and the major sign is placed.
Thus, the solution is given by all the values of "x" less than -5.
The solution set is: (-∞, - 5)
