Question

If x = 4 and y = 7 , evaluate the following expression:

3(3y - 4x)

Answer 1

the answer is 47

Explanation:

you have to look at the y as 7 plug the 7 in the parentheses on the left side of the minus sign and you get 63. Now look at the 4x. X is now replaced with 4. 4 times 4 is 16. 63 minus 16 is 47.

Answer 2

The answer is 15

Explanation:

The answer is 15 because I used the order of operations. So, first I calculated the paranthesis. Then I multiplied left and right and I got 15.
