Introduction to variable solver:

The Variable solver is the mathematical function to solve the equation of the one variable, two variables and also three variables. The variable solver is used to get the values for the given Algebraic equation. This variable solver is also used in the electronic circuits to find the voltage across the circuits, current and also the capacity of the circuit.


Examples for variable solver:


Example 1 for variable solver:

Find the value of x for the algebraic equation 5x + 4=94.

Solution:

The given equation is 5x + 4=94.

Subtract 4 on both sides of the algebraic equation.

5x + 4- 4= 94- 4

5x =90

Divide by 5 on both sides of the above algebraic equation

5x/5 = 90/5

x= 18

The value of x for the algebraic equation 5x + 4=94 is 18.

Example 2 for variable solver:

Find the value of x and y for the algebraic equations    2x+ 3y =4 and 2x- 3y =4.

Solution:

The given algebraic equations are 2x+ 3y =4 and             2x- 3y =4.

Add the two equations to get first the value of x.

2x+ 3y =4

2x- 3y = 4

______________

4x = 8

Divide 4 on both sides of the above equation.

4x/ 4 = 8/ 4

x= 2

To get the value of y substitute the value of x in the given equation. Take any one of the given equation to get the value of y.

Substitute the value of x in this algebraic equation    2x+ 3y =4.

2 (2) + 3y=4

4+ 3y =4

Subtract 4 from the above equation.

4-4 + 3y = 4-4

3y= 0

Divide 3 on both sides of the above quadratic equation to get the value of y.

3y/3 = 0/3

y= 0

The values of x and y for the given algebraic equations are x=2 and y=0.
