how should we solve a equation
Answers
Answer:
an equation is solved with a formula.
Step-by-step explanation:
there are so many different types of equation. that have different formulas.
Answer:
In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns. A solution is an assignment of values to the unknown variables that makes the equality in the equation true. In other words, a solution is a value or a collection of values (one for each unknown) such that, when substituted for the unknowns, the equation becomes an equality. A solution of an equation is often called a root of the equation, particularly but not only for polynomial equations. The set of all solutions of an equation is its solution set.
Step-by-step explanation:
An equation says that two things are equal. It will have an equals sign "=" like this:
x − 2 = 4
That equations says: what is on the left (x − 2) is equal to what is on the right (4)
So an equation is like a statement "this equals that"
What is a Solution?
A Solution is a value we can put in place of a variable (such as x) that makes the equation true.
Example: x − 2 = 4
When we put 6 in place of x we get:
6 − 2 = 4
which is true
So x = 6 is a solution.
How about other values for x ?
For x=5 we get "5−2=4" which is not true, so x=5 is not a solution.
For x=9 we get "9−2=4" which is not true, so x=9 is not a solution.
etc
In this case x = 6 is the only solution.
way o solve equation
1 Write the problem
2 Decide whether to use addition or subtraction to isolate the variable term.
3 Add or subtract the constant on both sides of the equation
