Question

If y=2 and z=3 what’s the value of 3y-8z

Answer 1

- 18

Explanation:

since y=2 and z=3,

Then, 3y = 3×2= 6

And 8z = 8×3 = 24

so 6 - 24 = -18

Answer 2

Answer: -18

Explanation:

We're asked to evaluate the expression 3y - 8z for z = 3 and y = 2.

So, what we do is we substitute these values into this expression, like this

⇒ 3(2) - 8(3)

⇒ 6 - 24

⇒ -18

Therefore the value of the expression is -18
