To see if 8 is the solution to the equation, 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 = 22
Parentheses...
3(8 - 2) + 4 = 22
8 - 2 <<<In the parentheses so you must solve first
6
so...
3(6) + 4 = 22
Multiplication...
3(6) + 4 = 22
3 * 6
18
so..
18 + 4 = 22
Addition...
18 + 4 = 22
18 + 4
22
so...
22 = 22
Are they equal to each other? YES!!!
8 is a solution to the equation 3 (x - 2) + 4 = 22
Hope this helped!
