You cannot at any time multiply by 0, divide by 0, or subtract to get any number in the equation

8+9+6+(1+2+3+4+5+7)^0 = 24\n\nX^(0) = 1

Just treat all other letters as constants. You can multiply, divide, add and subtract both sides of an equation and maintain the equality.

try working with BODMAS (BRACKETS Of Multiplication Division Addition Subtraction) and of course equalising the denominator. Hope that helps

or solve equation for x and y components separately. \nfor x    0 +3+?=0 \nfor y    3+0 +?=0

I too failed math but to me this is a logic question:\n0+0=0\nWhat else cloud it be?

well, take out 2x...2x(x-4)=0\nsolve 2x=0 and x-4=0\nx=0 or x=4

All real numbers except 0 and -1 because they would make the denominator equal to 0

You can't. Any equation like that where the answer isn't reasonably obvious is actually impossible to solve exactly. For example, if you had 2^a + a = 4, its impossible to get an exact answer (using square roots, logs, or whatever you want). Your only hope is to get an approximate answer via graphing or other approximation algorithms.\nOf course, you were lucky in that case :)

x can be zero to make the whole equation 0\n\n(2x-5) = 0...x = 5/2 plug it in and it does work\n\n(3x+9) = 0...x = -3 (but no negative reals)? so i guess that doesn't count?

u can't devide by (a-b) as (a-b)=0

grab a calculator and try 1.1 x = = = = =  until you get a number >2.\nthe first time you hit = is ^2, next is ^3 etc.  count.\n\nN=7

Multiply both sides by 0.\n\n8/2 * 0 = 0 * 0\n0 = 0\nProved

Absoultue zero in terms of Kelvin is impossible to obtain because there can never be nothing

Multiply or divide all components in one question to set the variables in the opposite questions to cancel out if you added the two problems together by combining like terms. For example:\n2x + 3y = -13  and 4x + y = -1\n\nTo keep this simple I will multiply all the components of the 2x + 3y = -13 equation by negative 2, resulting in:\n\n-4x - 6y = 26\n\nThen add the new equation to the other equation 4x + y = -1\n\n-4x -6y = 26\n4x + y = -1\n----------------\n0x -5y = 25  which simplifies to y = -5\n\nInsert the value found for y back into one of the original eqations and solve for x\n\n2x + 3(-5) = -13\n\n2x + -15 = -13\n\n2x = 2\n\nx = 1\n\nYour end result is x =1 and y = -5

what on earth...there's no equal sign, hence it's not even an equation, therefore there isn't even a single root.  what you have here is a mathematical expression.  x can be anything.

there is nothing to simplify.\n`

My old math teacher showed me this.\n\nSince A=B, then A-B=0, and you can't divide by 0
