If 9 is the solution of variable x in the equation (5x - 7)/2 = y, then the value of y is 28. Is the following statement true or false

Solution:

Let’s put x = 9 in the equation (5x - 7)/2 = y

[5(9) - 7]/2 = y

[45 - 7]/2 = y

y = 38/2

y = 19

Hence, if 9 is the solution of variable x in the equation (5x - 7)/2 = y, then the value of y is 9. False.

✦ Try This: If 5 is the solution of variable x in the equation (5x - 7)/2 = y, then the value of y is 14.

Let’s put x = 5 the equation (5x - 7)/2 = y

[5(5) - 7]/2 = y

[25 - 7]/2 = y

y = 18/2

y = 9

Hence, if 5 is the solution of variable x in the equation (5x - 7)/2 = y, then the value of y is 14. False.
