Question

I already made an attempt at this question and I would just like to check my answer z = ?

Answer 1

So we have the equation:

`(z+9)/(4)=2.1`

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

`z+9=8.4`

Then we subtract 9 on both sides to solve for z:

`z=-0.6`

Therefore the answer is z = -0.6.
