Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y)2.

How do you slove this problem 3x-111 x2 x?
There are some operators missing that make this rather ambiguous. If you mean: 3x - 111 + x2 = x and wish to solve for x, then here's the answer: x2 + 2x - 111 = 0 x2 + 2x + 1 = 112 (x + 1)2 = 112 x + 1 = ± √112 x = -1 ± 4√7 If you mean: 3x - 111 = x2 + x Then solving for x gives us this: x2 - 2x + 111 = 0 x2 - 2x + 1 = 112 (x - 1)2 = 112 x - 1 = ± √112 x = 1 ± 4√7 If you mean: 3x - 111 + x2 + x And want to simplify it, that would be: x2 + 4x - 111 Not much really, as it can't be factored further.
The sum of two numbers is 66 two times the larger number minus the smaller number is 177?
x + y = 66 where x > y 2x - y = 177 rearrange the top equation: y = 66 - x substitute into the bottom: 2x - (66 - x) = 177 2x - (-x) - 66 = 177 2x + x - 66 = 177 2x + x = 111 3x = 111 x = 111/3 = 37 substitute back into the first equation: 37 + y = 66 y = 66 - 37 = 29

What is the answer to 2x equals X plus 3?
2x = x+3 2x-x = 3 x = 3
2x -6 and x - 43?
2x - 6 = x - 43 2x = x - 37 x = -37
What are two consecutive integers which add up to 111?
X + (X+1) = 111; 2X + 1 = 111; 2X = 110; X = 55 and the other number is 56

What is x x 2x?
2x+x is 3x
What is the sum of 2x plus 1 and x times x minus 2x plus one?
(2x + 1) + (x*x - 2x + 1) = x^2 + 2x - 2x + 1 + 1 = x^2 + 2
Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
How do you solve x plus 2x equals 3?
2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3
How do you prove tan x plus tan x sec 2x equals tan 2x?
tan x + (tan x)(sec 2x) = tan 2x work dependently on the left sidetan x + (tan x)(sec 2x); factor out tan x= tan x(1 + sec 2x); sec 2x = 1/cos 2x= tan x(1 + 1/cos 2x); LCD = cos 2x= tan x[cos 2x + 1)/cos 2x]; tan x = sin x/cos x and cos 2x = 1 - 2 sin2 x= (sin x/cos x)[(1 - 2sin2 x + 1)/cos 2x]= (sin x/cos x)[2(1 - sin2 x)/cos 2x]; 1 - sin2 x = cos2 x= (sin x/cos x)[2cos2 x)/cos 2x]; simplify cos x= (2sin x cos x)/cos 2x; 2 sinx cos x = sin 2x= sin 2x/cos 2x= tan 2x
