Question

How do you evaluate the following expression when x = 3, y = 4, z = 5: for 2(z - x)?

Answer 1

`=color(blue)(4`

Explanation:

The expression is :
`2(z-x)`

We are provided with the value for the variables `z` and `x`

`z=color(blue)(5`
`x=color(blue)(3`

`2(z-x) = 2color(blue)((5-3)`

`=2 *2`

`=color(blue)(4`
