Question

Evaluate the expression for the given values.

mx−y when m=1, x=5x=5, and y=2

Enter your answer in the box.

Answer 1

Step 1) Start with the original expression

Step 2) Replace m with 1 (since m = 1)

Step 3) Replace x with 5 (since x = 5)

Step 4) Replace y with 2 (since y = 2). After this step we use PEMDAS to evaluate.

Step 5) Multiply (the M in PEMDAS)

Step 6) Subtract (the S in PEMDAS). Note how the S comes after the M. So subtraction is done after multiplication.

----------------------------------------------------------------

Step 1) m*x - y

Step 2) 1*x - y

Step 3) 1*5 - y

Step 4) 1*5 - 2

Step 5) 5 - 2

Step 6) 3

----------------------------------------------------------------

So the final answer is 3
