Hey there!
3x + z + 2y - 12
We know this information:
x = 3
y = 8
z = 5
With this information, we’ll just “fill in the blanks” (aka the parts with the exponents)
So, the expression would look like this:
(3 * 3) + 5 + (2 * 8) - 12
Now, we solve (see photo)
Therefore, the answer is 18
Hope this helps you!
God bless ❤️
