Answer 1

Answer:

X = 12

Step-by-step explanation:

Basically, just start with 11 and do all of the steps backwards, so multiply 11 by 5, which is 55, then add 2, 57. divide by 3, which is 19, then subtract 7, and you'll get the original number, 12.

Answer 2

Answer:

x = 12

Step-by-step explanation:

Following the steps in the flowchart

(1) Input the number x

x

(2) Add 7

x + 7

(3) Multiply by 3

3(x + 7)

= 3x + 21

(4) Subtract 2

3x + 21 - 2

= 3x + 19

(5) Divide by 5

$\frac{3x+19}{5}$

(6) Output the number 11

$\frac{3x+19}{5}$ = 11 ( multiply both sides by 5 )

3x + 19 = 55 ( subtract 19 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12
