Waht x what equals 198?

198 \n= 1 x 198 = -1 x -198\n= 2 x 99 = -2 x -99 \n= 3 x 66 = -3 x -66 \n= 6 x 33 = -6 x -33 \n= 9 x 22 =  -9 x -22 \n= 11 x 18 = -11 x -18

simply subtract 7 from both sides. This leave you with\n\nx<_3

let x = smaller number\n2x + 8 = larger number\n2(2x + 8) + 3x = 65\n4x + 16 + 3x = 65\n7x + 16 - 16 = 65 - 16\n7x = 49\n7x/7 = 49/7\nx =7

Yep, it's 202.  Factor out the x and add the resulting cofactors\nin pairs whose sums are 100.\n\nx[(1+99)+(2+98)+...+\n(49+51)+50+100] =\nx[5050]  Now factor 5050 to its primes.\n\n  you get  2,5,5,101 so all you need are two factors\nof 2 and 101 to get all primes in pairs. Thus the answer is 202.\n\n202X4950=1020100 = (1010)^2\n\n Pretty clean , eh?

x≠０\ncuz if x=0, (x-7)/x^3 is meaningless

Let x = 0.99999999999999...\n\nThen,\n10x = 9.99999999999999.....\nSubtract x\n\n10x=9.99999999999999.....\nx = 0.99999999999999.....\n\n9x = 9\nTherefore \nx = 1\nand\n0.99999999999999999..... = 1\n\nQED ^_^

X  = Nothing \nor X  = 24th letter of the English Alphabet.\n\nAm I too clever or do I get the 10 points for being a smart ass?

12 simply place the 1 where the x is\n\n(1+3)(1+2)\n4*3\n12

it is 178 * 177 !\n\nthis can always be computed.

Sum = 1 + 2 + 3 + .............. + 98 + 99 + 100\nSum = 100 + 99 + 98 + .............. + 3 + 2 + 1\n--------------------------- -----------------------------\n2 x Sum = 101 + 101 + 101 + .... + 101 + 101 + 101\nSo Sum = ½ (100 * 101)\n= 5050

your variable is x so you replace that with 8, since x=8     since there are no signs between the 9 and x  in  9x  , that means to multiply them  so that is 72       so your answer is 72 + 5 or 77  , hope that helps

x = loser\nx + 220 = winner\n\nx + (x+220) = 810\n2x + 220 = 810\n2x = 810-220\n2x = 590\nx = 295\n\nTherefore  - The loser had 295 votes and the winner had 295 + 220 = 515\n\n295 + 515 = 810
