-4(2x+8)=32\n-8x-32=32\n-8x=64\nx=-8\n\nEDIT: The guy above missed a sign.  Insert -8 into the original equation to see if it checks out (it does).

I think this is also the 'trial and error method'\nYou will have an equation where you do not know the value of x.\nKeep on substituting different values of x into the equation until you come up with the right answer.\nIf you are lucky, you may have been told that x lies somewhere between 2 values.\nBest way to do it is to choose a number, get the answer, then choose another number a fair bit larger than the first. If the answer you want is between these 2 values, choose a number about half way between the 2 and so on.

Use log you will find\n\nor put\n\nx=3.597285024\n\nIts done

okay well pretty much you have to solve for  x\nso inorder to get X by itslef you have to -4 from -8 like so:\n2x + 4-4 = –8-4\n2x=-12\nnow you still have 2X but now you can divide the 2 into -12\nx= \nI won't give you the answer but you should be able to find the answer!!!

6(x-4)=30\nx-4=5\nx=9

Substitute 2 for x and solve for c.\n2^2-3(2)+c=0\nRemember do powers, then multiplication, then subtraction.

x = -7\n\nMultiply two negatives and you get a positive

I think the best answer would\nbe to give y in terms of x.\nThis is :\ny = (6302869x^2 - 384932345355.22x - 59096) / (231689354x + 23431653.57948)

take out the x\nx(a-b)=6\nx=6/(a-b)

x = -b +(or)- sqrt(b^2 - 4ac)\n    -------------------------\n               2a

(x/2)-4=8\n(x/2)=12\nx=24

Just plug 0 in the function whenever you see y.\n\n4x + 3(0) + 24 = 0\n4x + 0 + 24 = 0  \n\nThen solve for x.\n\n4x = -24\nx = -6

Ok...\nI see what you are doing...\nYou merely substitute the number in for x...\nso the problem becomes 6-2*(-1)\n6+2\n8

x = 15\n\n10 - 15 = -5

Let,the number be x\nkTherefore according to the problem\n10-2x=x+3\n=>-2x-x=3-10\n=>-3x=-7\nx=-7/-3=7/3=2 1/3\nTherefore the number is 2 1/3

-3 <4x\n x < -3/4\n solution set : {- infinity ,.............,-3/4}

As stated by katie, there is no " x ". However, check this out. 4n/5 * 5 = -8 * 5\n     4n = -40\n      n = -10 \n\nPretty simple as you can see. Good luck !
