Adding mistake! lol
"2x + 3x = 6 combine like terms;
6x = 6"
its meant to be
5x = 6
x = 1.2
so for the most part youwere correct just remember to recheck your calculation
I just worked out a problem that gave me and answer of 1 but when checked with the correct answer it was 1.2......Here is the problem
Erin can paint a room in 3hrs and her hubby can do it in 2hrs, how long will it take both to paint the room together?! (simplified the question)
Ok! so knowing that
Erin=3x and Hubby=2x the problem then is written like this....(right?)
1x over 3 plus 1x over 2 equals 1
1x + 1x = 1
ok now the LCD is 6 and then multiply all by (6)
(6) 1x + (6) 1x = 1(6)
cancel the 6 and the 3 = 2 and the 6 and the 2 = 3 right!?
so now we have
2x + 3x = 6 combine like terms;
6x = 6
and then solve for
so far so good or did I dushbag it somewhere?!
