Answer 2

z = 120

Explanation:

The given equation is z ÷ 12 = 10

Here we need to solve for z.

Since we have 12 in the division we need to inverse operation of division to get rid off 12.

The inverse operation of division is multiplication. So we need to multiply both sides by 12, we get

`12.(z)/(12) = 10 times 12`

z = 120

Check

120 ÷ 12 = 10

10 = 10

True
