Question

If 2Z-3=7, then the value of Z is *

​

Answer 1

Answer:

2Z=7+3

2Z=10

Z=10/2

Z=5

Answer 2

Answer:-

Given that,

2Z-3=7

We have to find the value of Z

So,

2Z-3=7

Adding 3 to both sides, we get,

2Z-3+3=7+3

Or,

2Z=10

Dividing both side by 2, we get,

2Z/2=10/2

Or,

Z=5

Hence, the value of Z is 5.

Check:-

2Z-3

=2*5-3

=10-3

=7

Hence, the value of Z is 7
