The given equation is [tex] z-3 = 22 [/tex]
We have to solve the equation for z.
To solve it for z, we have to move 3 to the right side. 3 is subtracted in the left side, so to get rid of it and move it to right side we have to use reverse operation of subtraction. The reverse operation of subtraction is addition. So to move 3 to the right side we will have to add 3 to both sides.
[tex] z-3 = 22 [/tex]
[tex] z-3+3 = 22+3 [/tex]
[tex] z = 22+3 [/tex]
[tex] z = 25 [/tex]
So we have got the required answer.
The correct option is c here.
we are given
[tex] z-3=22 [/tex]
Since, we have to find z
so, we isolate z on left side
so, we will move 3 on other sides
that's why we add both sides 3
[tex] z-3+3=22+3 [/tex]
now, we can add numbers
[tex] z+0=22+3 [/tex]
[tex] z=25 [/tex]...........Answer
