Answer 1

To find the value of z that makes the equation true, we can isolate the variable z by performing the necessary operations:

9z - 7 = 47

Adding 7 to both sides of the equation:

9z - 7 + 7 = 47 + 7

9z = 54

Dividing both sides of the equation by 9:

(9z)/9 = 54/9

z = 6

Therefore, the value of z that makes the equation true is 6.
