3x+9=2x+10
3x+9-2x=10
9+x=10
x=1
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
-x + 9 - 2x = -21 combine like terms -x and -2x isolate -3x by subtracting 9 from both sides divide both sides by -3 -3x + 9 = -21 - 9 - 9 -3x = -30 x = 10
10 - 3x = x - 2x + 40 10 - 3x = - x + 40 10 - 40 = 3x - x -30 = 2x -15 = x
10 + 2(x - 1) + 7 x 3x + 1 =10 + 2x - 2 + (7 x 3x) + 1 =10 + 2x - 2 + 21x + 1 =2x + 21x + 10 - 2 + 1 =23x + 9
2x+10=9+11-3x2x+10=20-3x5x+10=205x=10x=2
2(x+5) =3X+1 => 2x+10-3x-1=0. => -x+9 => x=9
If you mean: (3x-14)(2x+10) then it is the factored version of 6x^2 +2x -140
6x2 - 13x - 63 = 6x2 + 14x - 27x - 63 = 2x(3x + 7) - 9(3x + 7) = (3x + 7)(2x - 9)
-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
Here is how you solve this problem... 5x*4-3x*5*2x-9= (Combine like-terms) 5x-3x*2x= 2x*2x=(2x)2 (Add the rest of the problem) (2x)2*4*5-9=(2x)2*20-9 (2x)2*11 (2x)2 *11= your answer
