An equation is a condition based on a variable that satisfied both sides of RHS (Right Hand Side) and LHS (LHS). We have learnt in class VIth, Algebra.
Hear we learn about the Equations that has in Simple formed.
In this section we learn and solve the equation based game. The equation based game blow the light of idea in mind of several thoughts.
For Example −
You and your brother has play some mind game. Your brother says to you that let's suppose any number in your mind and multiply that number with 4 and add 5 in that and tell that final resulted number 65 and your friend will tell you that number which was thinked. this is possible that's because of equation solving.
On above the example here we learn how setting the equation.
See how-
Let's x is a variable that multiply with 4 and add 5 in that-
(x * 4) + 5 = 65
4x + 5 = 65
4x = 64 - 5
4x = 60
X = 60/4 = 15
The word variable means something that can vary, i.e. change. A variable takes on
different numerical values; its value is not fixed. We learn about this is pervious classe.
WHAT EQUATION IS?
An equation is a condition on a variable. The condition is that two expressions should have equal value. Note that at least one of the two expressions must contain the variable.
An equation remains the same, when the expressions on the left and on the right are interchanged.
Here we learn about transposing a number, i.e., moving it from one side to the other. We can transpose a number instead of adding or subtracting it from both sides of the equation.
Changing side is called transposing. While transposing a number, we change its sign.
Transposing a number (i.e., changing the side of the number) is the same as adding or subtracting the number from both sides.
We learnt about the how solve the equations.
Equation ⟶ Solution (normal path)
Solution ⟶ Equation (reverse path)
Applications of Simple Equations to Practical Situations
We have learn more now we are ready to solve puzzles/problems from practical situations. The method is first to form equations corresponding to such situations and then to solve those equations to give the solution to the puzzles/problems.
