We can say equation solver is a kind of tool to solve the equation. We can say an equation is of the form A = B. Here A and B are expressions having unknowns. For example, 3 is the unique solution of the equation x +  4 = 7. In other words we can say an equation is a kind mathematical statement that has two expressions divide by an equal sign. 

Example 1: Solve the equation 3x + 5 = 13 – x.

Solution: The given equation is 3x + 5 = 13 – x

Now we can add -5 on both sides of the equality

3x + 5 – 5= 13 – x – 5

3x = 8 – x

Now we can add x on both sides of the equality 3x + x = 8 – x + x

4x = 8

Therefore, x = 2.

Example 2: Solve the equation 2x + 21 = 9x – 14 .

Solution: The given equation is 2x + 21 = 9x – 14

Now we can add 14 on both sides of the equality

2x + 21 +14 = 9x – 14 – 14

2x + 35 = 9x

Now we can add – 2x on both sides of the equality 2x + 35 – 2x = 9x – 2x

35 = 7x

Now we can divide this equation by 7, then we get 35/7 = 7x/7

  5 = x

Therefore, solution of the given equation is x = 5.
