Explanation Given information: The provided equation is 30 = 6 ( 2 A + 3 ) . Formula used: To solve the equations containing parenthesis, Step1: First eliminate the parentheses from the equation. a) Multiply the number which is outside of the parenthesis to each addends inside of the parenthesis. b) After multiplying write the resulting equation as addition or subtraction as indicated. Step2: Simplify the resultant equations obtained. Step3: Finally, check the solution from the original equation. Calculation: Consider the provided equation is, 30 = 6 ( 2 A + 3 ) In first, eliminate the parentheses and multiply 6 by 2 A and 6 by 3. 30 = 6 ( 2 A + 3 ) 30 = 12 A + 18 After multiplying show to the resulting product as addend, 30 = 12 A + 18 30 − 18 = 12 A + 18 − 18 12 = 12 A Divided both side of the equation by 12

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.
