Question

If x = 5 and y = 3, then xy - 2x =

Answer 1

5

Explanation:

First, we will need to replace the x and ys with the values.

So the equation will be this:

(5) x (3) - 2(5)

Now, following PEMDAS, we will do the M in PEMDAS (aka multiplication left to right)

Now our simplified expression is this:

15 - 10

Now, following PEMDAS, we will do the S in PEMDAS (aka subtraction left to right)

Therefore, the answer is: 5
