what is simple linear equation
Answers
Answer:
In general linear equations are found in most calculations in science.In chemistry for example,linear equations are used in balancing chemical equations.In physics newton's laws of motion are mostly linear equations.
Definiton
A linear equation is defined as an equation where the greater power of the unknown is one.
Examplesx+5=125x-3=44x=9
In all the above examples the highest power of x is one
Solving simple linear equations
To solve simple linear equations the following points should be noted;
the sign of any term changes when it is moved from either side of the equal sign to the other e.g from the left-handside{L.H.S}to the right-handside{R.H.S}or vice visa.Any operation you do to the left,you must do to the right,this is because the equation will change otherwise.Example1
Solve the equation x+3=4
solve the equation 33x-22=44
Solution
since x is on the left-handside of the equal sign ,we simply move 3 to the other side of the equal sign giving; x = 4-3 therefore x = 1 is the answer.
Simple linear equations in one variable - this means there will be no x2 terms and no terms involving higher powers of x. ... To solve such an equation means to find a value for x which makes the left- and right-hand sides equal.
