Question 28240: 2x+3x-2=3x-1+3x+1+3x
Easy! combine all like terms on each side: all numbers with an X and those without:
So,2x+3x=5x
and 3x+3x=6x
and 1+1=2
Then rewrite:5x-2=6x+2
Now pick a side of the equal sign to put consants and move varibles on to opposite side:
So,
5x-2=6x+2 becomes -x=4
divide by -1
and the answer is x=-4
Check by sub. -4 for x in original problem: 2x+3x-2=3x-1+3x+1+3x and you should come out with answer of 0=0

Question 28775: Hello! I'm making my way through a book called "The Mathematics of Games and Gambling" by Edward Packel. There's an algebraic equation therein which goes like this:
x=4pq-5(1-q)-2(1-p)q+3(1-p)(1-q). The author partially reduces this expression to the following:
x=14pq-8p-5q+3. I don't understand how he arrived at that point. Using my own highly dodgy math skills, I came up with the following:
x=9pq-5p+2q-2. I tried the "collecting like terms" operation, but I obviously veered off the right path somewhere. Could someone show me the light here, please? With many thanks, RR
