It does: suppose you want to check a division, e.g. 18/3=6. Then you know 18 = 6*3. Now -4/4 = ???, then 4 * ???= -4. What number is ???
1
No, because 4*1=4 and not -4
-1
OK, so -4/4 = -1 Now you have to do: 20x/4
5
You lost x
5x
Done!
so thats my final answer are my final equation
You have -4 and 5x, so the final answer is... -4+5x
how bout this one \[-\frac{ 1 }{ 2 }(4-6a)\]
Use the distributive property: a(b-c)=ab-ac
I dont knoe the distributie Prop
It tells you how to get rid of the brackets! So you have to multiply -1/2 with 4 and also multiply -1/2 with -6a
okay I see
What do you get?
how do I multiply a fraction in to a number
Just forget the "-" for a while. 1/2 * 4 means you have four halves. How many is that?
2 wholes
OK. Now remember that if you multiply a negative number with a positive number, the outcome is negative. So: -1/2 * 4 = ...
-2
Right!, now the other one...
so for the other half it be-3 the i would be left with(-2- -3) and my answer be -5
You have to multiply, so -1/2 * -6a = ...
6 isn't negative that was the subtraction sign
OK, so save it for later. So: -1/2 * 6a = ...
-3
You lost the a
-3a ugh srry:p
so then my equation would be(-2 - -3a)
the my answer should be -5a right
No, -2 hasn't got an a with it, so you can't add it to 3a
So it would be -2+3a
-- = +
so it be 1a right
No, it would be -2+3a. This cannot be written shorter! If it was -2a+3a this would be 1a or a.
oh okay got it
