Is 8 a solution to the equation below? Yes or No?<br><br><br> 3(x - 2) + 4 = 22
Simora [160]

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!

Betty is canning 104 pears and 126 apples separately. Each jar holds 8 pears or 6 apples. How many jars does Betty need
Nina [5.8K]
For the pears, Betty will need 13 jars. I know this because I divided 104 by 8. I did the same for the apples. 126 divided by 6. You get 21. Have a nice day!
