Assuming you mean 3x - 2 = 9x - 5...
3x - 2 = 9x - 5
3x + 3 = 9x
3 = 6x
0.5 = x
To solve the expression ( 14 + 3(3x + 3)(x - 5) ), first simplify the term ( 3(3x + 3) ) by distributing the 3, giving ( 9x + 9 ). Next, multiply this result by ( (x - 5) ) using the distributive property: ( (9x + 9)(x - 5) = 9x^2 - 45x + 9x - 45 = 9x^2 - 36x - 45 ). Finally, combine this with the 14 to get ( 9x^2 - 36x - 45 + 14 = 9x^2 - 36x - 31 ).
9x2-9x-10 = (3x+2)(3x-5) when factored
The expression (9x^2 + 30x + 25) can be factored as ((3x + 5)^2). This is because it is a perfect square trinomial, where (9x^2) is ((3x)^2), (25) is (5^2), and (30x) is (2 \cdot 3x \cdot 5). Therefore, the factored form is ((3x + 5)(3x + 5)) or simply ((3x + 5)^2).
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
This simplifies to 6x = -3, so x = -0.5 Check: (3 x -0.5) + 2 = (9 x -0.5) + 5 ie -1.5 + 2 = -4.5 + 5 0.5 = 0.5 QED3x + 2 = 9x + 5 3x - 9x + 2 - 2 = 9x - 9x + 5 - 2-6x = 3 -6x/-6 = 3/-6 x = -1/2 or x = -0.5
9x2-9x-10 = (3x+2)(3x-5) when factored
9x2 + 9x - 10 =(3x - 2)(3x + 5)
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
That can be factored to (3x - 5)(3x - 5) or (3x - 5)2

This simplifies to 6x = -3, so x = -0.5 Check: (3 x -0.5) + 2 = (9 x -0.5) + 5 ie -1.5 + 2 = -4.5 + 5 0.5 = 0.5 QED3x + 2 = 9x + 5 3x - 9x + 2 - 2 = 9x - 9x + 5 - 2-6x = 3 -6x/-6 = 3/-6 x = -1/2 or x = -0.5
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5
Okay, so -9x = 3x-10 first we add ten to both sides 10-9x=3x next add 9x to both sides 10=12x now divide both sides by 12 10/12=x reduce 5/6 The check... -9 x (5/6) = -45/6 reduced is -15/2 3 x 5/6 = 15/6 15/6 - 10 = 15/6 - 60/6 = -45/6 or -15/2 Therefore we have the correct answer :D
3x - 5 = 2y3/2X - 5/2 = y
3x2-9x-30 =3x2+6x-15x-30 =3x(x+2)-15(x+2) =(3x-15)(x+2) OR 3(x - 5)(x+2)
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
12X + 5 = 9X - 26 subtract 9X from each side 12X - 9X + 5 = 9X - 9X - 26 3X + 5 = - 26 subtract 5 from each side 3X + 5 - 5 = - 26 - 5 3X = - 31 divide both sides integers by 3 (3/3)X = - 31/3 X = - 31/3 ---------------------
