4/x - 1 + 6/3x +1 = 15/3x + 1 4/x - 1 + 2/x +1 = 5/x + 1 4/x + 2/x - 5/x = 1 + 1 -1 1/x = 1 x = 1
You can divide the integers in this case - 4 divided by 2 and 9 divided by 3. You would get 2 over x plus 3 over x. 4/2x + 9/3x = 2/x + 3/x = 5/x
(x - 3x - 6) / 6 = (3x + 2) / 3 ∴3x - 9x - 18 = 18x + 12 ∴3x - 9x - 18x = 12 - 18 ∴-24x = -6 ∴ x = 1/4
Your equations are not worded properly.
It is: 3x^2 +15x +12
(x - 3x - 6) / 6 = (3x + 2) / 2 ∴2(3x + 2) = 6(3x + 2) ∴6x + 4 = 18x = 12 ∴12x = -8 ∴x = -2/3
9x2 + 12x + 4 = 9x2 + 6x + 6x + 4 = 3x(3x + 2) + 2(3x + 2) = (3x + 2)(3x + 2) = (3x + 2)2
4/x - 1 + 6/3x +1 = 15/3x + 1 4/x - 1 + 2/x +1 = 5/x + 1 4/x + 2/x - 5/x = 1 + 1 -1 1/x = 1 x = 1
The sum of 3x plus 2 and -4 plus 3 is 3x+1 if the equation is (3x+2)+(-4+3). If they are two separate questions, 3x+2 remains as itself while -4+3=-1.
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
You can divide the integers in this case - 4 divided by 2 and 9 divided by 3. You would get 2 over x plus 3 over x. 4/2x + 9/3x = 2/x + 3/x = 5/x
(x - 3x - 6) / 6 = (3x + 2) / 3 ∴3x - 9x - 18 = 18x + 12 ∴3x - 9x - 18x = 12 - 18 ∴-24x = -6 ∴ x = 1/4
I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
Your equations are not worded properly.
2(3x + 4) + 5x - 2
It is: 3x^2 +15x +12
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
