x+5+3x-7+9x+3-4x Collect like terms: 9x+1
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9
You write it out with less digits but will be able to get the same answer. Example: 9(x+3)=9x+27
12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!

x+5+3x-7+9x+3-4x Collect like terms: 9x+1
To simplify x3-9x, you factor out the x, leaving you with x(x2-9). You can then take the square root of both numbers and end up with x(x+3)(x-3).
If you mean 9x+x then it is 10x when simplified
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
9x-8=7x-3 9x-7x=-3+8 2x=5 x=5/2 x=2.5
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 ---------------------
(6x^3-9x^2) / (2x-3) = 3x^2((2x-3) / (2x-3) = 3 x ^2 (3 x squared)
x-7.(-9)x-15
(-9x^2/√x) + 4= [-9x^2/x^(1/2)] + 4= (-9x^2)[x^(-1/2)] + 4= -9x^[2 + (-1/2)] + 4= -9x^(2 - 1/2) + 4= -9x^(3/2) + 4= -9√x^3 + 4= -9√[(x^2)(x)] + 4= -9x√x + 4Or,(-9x^2/√x) + 4= [(-9x^2)(√x)/(√x)(√x)] + 4= [(-9x^2)(√x)/√x^2] + 4= [-9(x)(x)(√x)/x] + 4 simplify x= -9x√x + 4
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
5*2+9x-2=0 so, going by BODMAS rule 10+9x-2=0 9x=-10+2 9x=-8 x=-8/9 I think!!
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9
