if x=-3,y=2,Z=5 find the value value of x-y+2z

Question

Its a algebra questions I don't full understand how to get a ansee

Answer 1

The question is giving us the values to the variables. So we need to plug them into the expression:

(-3) - 2 + 2 * 5

Remember the order of operation--multiplication takes place before addition and subtraction:

(-3) - 2 + 10

Now we can add/subtract in any order, so if we rearrange this a little, we have:

10 - 3 - 2

I'm sure you can solve that on your own.
