Best ResponseYou've already chosen the best response.0It is simple matching of numbers and letters, followed by arithmetic. \[x=4\]\[y=3\]\[m=6\] Now take the equation and replace the letters with the corresponding numbers: \[2xym = 2(4)(3)(6)\] What does that equal?

Best ResponseYou've already chosen the best response.0I did. All you have to do is the arithmetic. What is 2*(4)*3  6 ?

Best ResponseYou've already chosen the best response.0Yes, 2*4 = 8. 2*(4) = 8, because a positive number (2) times a negative number (4) gives you a negative result (8). A negative number times a negative number gives you a positive result, and of course a positive number times a positive number also gives you a positive result. So, we've gotten the first multiplication done: \[2*(4)*3  6 = (8)*3  6\] What is (8) * 3?

Best ResponseYou've already chosen the best response.0If you're at 24 on the number line, and you go 6 units to the left (subtracting 6 = moving 6 units to the left on the number line), where do you end up?

Best ResponseYou've already chosen the best response.024  6 what is 24 + 6? 24 6 is the same thing, with a  sign in front...

Best ResponseYou've already chosen the best response.04 + 6 = 10, doesn't it? So 24 + 6 = 20+10 = 30. Similarly, 24  6 = 30

Best ResponseYou've already chosen the best response.0\[x=4\]\[y=3\]\[m=6\]First substitute in value of \(x\): \[2xym = 2(4)ym\]Now \(y\): \[2xym = 2(4)(3) m \]Now \(m\): \[2xym = 2(4)(3)  (6)\]Do the arithmetic: \[2xym = 2(4)(3)(6) = (8)(3)6 = 24  6 = 30\]

Best ResponseYou've already chosen the best response.0Before anything else you need to learn basic arithmetic, this is a elementary school skill. You should be able to add numbers under 100 together easily. For example: 58+12 = 70 70  30=40 3911=28 1112=1 245=47 You NEED to be able to do this quickly and accurately. You can't add 24 and 6 and get 31... You need to think what 4+6 is...10! So how could the number end in 1? From there the problem is asking to make a simple substitution. If I have: a*b  c with a = 2, b = 3, and c = 4 then it's simply 2*(3)  4 = 64=10. Apply this to your current problem and any similar problem.
