Explanation Given Information: The provided equation is 5 ( x − 3 ) = 21 . Formula used: Steps to solve an equation, Step 1: First remove all the parentheses, by distributed property a ( b + c ) = a ⋅ b + a ⋅ c . Step 2: Perform addition or subtraction operation in like terms. Step 3: To make the variable term in one side, add or subtract by one variable term in the both sides of the equation. Step 4: To make the variable term be alone, remove the constant term from the side where the variable term is present by using add or subtract operation in the both sides of the equation. Step 5: Solve the resultant equation. Step 6: Check the solution by substitute root in the provided equation, if the left and right side value will be equal then the resultant root will be correct. Calculation: Consider the provided equation, 5 ( x − 3 ) = 21 , First remove the parentheses, by distributed property, 5 x − 15 = 21 Now, combine like terms, there are no like terms, 5 x − 15 = 21 Now, make the variable term be alone, add 15 in the both sides of the above equation, 5 x − 15 + 15 = 21 <

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
