Oh, dude, 2x in math just means you're multiplying 2 by x. It's like saying, "Hey, let's take 2 and x and make them best friends by multiplying them together." So, if x is 5, then 2x would be 2 times 5, which equals 10. Math can be cool like that, you know?
cl in maths means centiliter :)
"Like terms" are terms that have the same variables, but possibly with different numbers. "Collect" means to put them together - add the numbers. For example, in an expression such as: 5x + 3y - 2x You can combine the "x" terms: (5x - 2x) + 3y and add the numbers (this is justified by the distributive property: (5x - 2x) + 3y = (5 - 2)x + 3y = 3x + 3y

2x-5=15 +5 +5 2x=-10 --- --- 2x 2x x=-5 I hope it helped. i showed the work the best i could. ---- that means divide + is add, obviously and - means negative. Your welcome.(:
