Question

(4x-12) + ( 1/2x y -10) for x=4 and y=6

Answer 1

The answer would be 8

Answer 2

Answer: (4x-12) + ( 1/2x y -10) = 6

Explanation:

First, input 4 for x and 6 for y into the equation so it looks like this:

(4(4)-12) + (1/2(4)(6)-10)

Now solve inside the parentheses starting with the first one. 4 * 4 = 16 so the inside of the first parentheses should look like (16 - 12) which equals 4.

For the second set of parentheses, 1/2 * 4 * 6 = 12, so the inside of that parentheses would look like (12 - 10), which equals 2.

At this point, the equation should look like this: (4) + (2). If you add those two together, your answer should be 6.
