5x square
4x + -x = 3x
5x + x = 5x Squared (5x^2) x + x equals 2 x's = 2 = squared - very simple & logic. no its not simple and logic 5x^2 is the result of 5x times x. 5x plus x is 6x. Think of the x as 1x not x so 1x + 5x= 6x. That's simple and logic.
x = .5x - 4. Get all of the x's on one side: x - .5x = .5x - .5x -4 ---> .5x = -4 Multiply each side by 2. x = -8
3x - 5x + x = -x

5x x 4x = 20x^2 5x + x + 4x = 10x
Assuming the angles are expressed in radians:sin(5x) + sin(x) = 0∴ sin(5x) = -sin(x)∴ 5x = x + π∴ x = π/4On the other hand, if your angles are in degrees, then the answer would be:sin(5x) + sin(x) = 0∴ sin(5x) = -sin(x)∴ 5x = x + 180∴ x = 180°/4∴ x = 45°
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
5x+x >100
-43
5x - 3 + x - 9 = 5x Bring like terms together of the left side: 5x + x - 3 - 9 = 5x Combine like terms: 6x - 12 = 5x Add 12 to both sides: 6x = 5x + 12 Subtract 5x from both sides: x = 12
