To find the opposite, or the additive inverse, just change the sign to the opposite sign.\nIf it's positive, then make it negative.\nIf it's negative, then make it positive.

This one is trickier - ln-2/x wasn't allowed on the source. I tried the following:\n\nln[e]-2/x ==> 1-2/x ==> 2/x^2\nln[2/x] ==> -1/x\n\nI hope this helps.

f(x)=Int(f'(y), 0, x)-f(0) => yes, they're opposite operation, but if x has a given value, e.g. x=2, 3...no, they're not, b/c in that case, the RHS of the previous egality is a real number, not a function

Remember - a negative exponent is an inverse.  If all you are doing is multiplying and dividing, life is easy.\n\n(3a^-7 b^7)/(9a^7 b^-5)\n\nFirst, move the negatives from where they are to the other side of the miniscis:\n\n= (3 b^7 b^5)/(9 a^7 a^7)\n\n(You can verify this by rewriting, for instance, a^-7 as 1/a^7 and simplifying, but I promise you this works.)\n\nNow:  3/9 = 1/3\n\nb^7 b^5 = b^12\n\na^7 a^7 = a^14\n\nSo, b^12/(3 a^14) and we're done.\n\nIf there were addition and subtraction in the problem, then it gets an order of magnitude harder.  Then, there is no substitute for rewriting the negative exponents as reciprocals and simplifying from there.\n\nHope this helps.

For the first problem, subtract 2/3x on both sides:\n6y=-2/3x+1\n\nDivide 6 on both sides:\ny=-2/18x+1/6\ny=-1/9x+1/6\nSlope:-1/9\n\nFor the other problem, the inverse of -1/3 is 3:\n-1/(-1/3)\n-1*-3=3

1.1 and -1.1\nbut you don't need to round it, that is the exact answer.

You take each operation that is with the variable, and do its reverse to both sides.\n\n    m - 23 = 33\n    m - 23 + 23 = 33 + 23\n    \nSince (-23 + 23) = 0, \n\nm - 0 = 56\nm = 56\n\nThat way, the variable is by itself, and all the numbers are on the other side.

It equals (2/3)*pi.   It does not equal (-1/3)*pi  -- that would be (-inverse cosine (-1/2)).
