Question

(x-12)÷y+zx= -23 y= -5 z= -10

Answer 1

Given the below expression;

`(x-12)/(y)+z`

Let's go ahead and evaluate when x = -23, y= -5 and z = -10;

`\begin{gathered} ((-23)-12)/((-5))+(-10)_{} \\ \end{gathered}`

Let's clear off the parentheses being mindful of the signs;

`\begin{gathered} (-23-12)/(-5-10) \\ =(-35)/(-15) \\ =(7)/(3) \end{gathered}`

Therefore, the answer is 7/3.
