The variable is x. Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question. There is no visible symbol between 5x and 5.

The square root cannot be simplified.
5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
0. 6x + 3 = 5x + 141. 6x = 5x + 11 [subtracting 3]2. x = 11 [subtracting 5x]
2x square root 6x y squared
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
-2 and -3Check:(-2) + (-3) = -5(-2)(-3) = 6Thus -2 and -3 are not the required numbers. let's find them: x + y = -6xy = -5 y = -x -6x(-x - 6) = -5-x^2 - 6x = -5x^2 + 6x = 5x^2 + 6x + 9 = 5 + 9(x + 3)^2 = 14x + 3 = (+ & -)square root of 14x = -3 (+ & -)square root of 14x = -3 + square root of 14 or x = - 3 - square root of 14y = -x - 6y = 3 - square root of 14 - 6 or y = 3 + square root of 14 - 6y = -3 - square root of 14 or y = -3 + square root of 14Check:(-3 + square root of 14) + (-3 - square root of 14) = -6(-3 + square root of 14)(-3 - square root of 14) = -5 ?(-3)^2 - (square root of 14)^2 = -5 ?9 - 14 = -5Check also tow other numbers.
6x + 5x = 11x
It is: 5x times 6x = 30x^2
The square root cannot be simplified.
5x^2 + 6x - 2 doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (-3 plus or minus the square root of 19) divided by 5. x = 0.2717797887081348 x = -1.4717797887081348
6x
-6x+3 = -7-5x 7+3 = 6x-5x 10=x
If the square root of 6x-2=4 than we can square both sides and we have 6x-2=16 or 6x=18 and the solution set is the set that contains the number 3.
√(36x4) is written as: √((6x²)²) Then, this is evaluated to 6x².
root (6x - 2) = 4 therefore 6x - 2 = 16 therefore 6x = 16 + 2 therefore x = 3
x^2 - 6x + 5x + 7 = 0 => x^2 - x + 7 = 0The roots of this equation are0.5 - 2.5981*i and 0.5 + 2.5981*i where iis the imaginary square root of -1.
-5x+1 = 6x -5x-6x = -1 -11x = -1 x = 1/11
