Question

What is the value of the expression 3y−zy+5z when y = 6 and z = 2? 1. 1 2. 3 3. 4 4. 16 There is a pic too plz help...fast!!!!

Answer 1

`\Huge \boxed{1}`

Explanation:

`\displaystyle (3y-z)/(y+5z)`

Let y = 6 and z = 2.

`\Rightarrow \displaystyle (3(6)-2)/(6+5(2))`

Evaluate the expression.

`\Rightarrow \displaystyle (18-2)/(6+10)`

`\Rightarrow \displaystyle (16)/(16)`

`\Rightarrow 1`

The value of the expression when y = 6 and z = 2 is 1.

Answer 2

The answer is 1

Explanation:

`(3y - z)/(y + 5z)`

To find the value of the expression when

y = 6 and when z = 2 , substitute the values into the above formula and solve.

That's

`(3(6) - 2)/(6 + 5(2)) \\ = (18 - 2)/(6 + 10) \\ (16)/(16)`

We have the final answer as

1

Hope this helps you
