Q:

Is 8 a solution to the equation below? Yes or No?3(x - 2) + 4 = 22

Accepted Solution

A:
To see if 8 is the solution to the equation, Β 3 (x - 2) + 4 = 22, you must replace x with 8 and solve using the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction) REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS . If the sides are equal to each other then 8 IS a solution.3(8 - 2) + 4 = 22Parentheses...3(8 - 2) + 4 = 228 - 2 <<<In the parentheses so you must solve first6so...3(6) + 4 = 22Multiplication...3(6) + 4 = 223 * 618so..18 + 4 = 22Addition...18 + 4 = 2218 + 422so...22 = 22Are they equal to each other? YES!!!8 is a solution to the equation 3 (x - 2) + 4 = 22Hope this helped! ~Just a girl in love with Shawn Mendes
