what would 2(3x+1) = 9x-1 be?
959472
2(3x+1)=9x-1\n\nFirst you multiply 2 times (3x+1) \n\n6x+2 = 9x -1\n\nthen you subtract 6x from each side \n\n2 = 3x - 1\n\nthen you add 1 to both sides\n\n3 = 3x \n\nDivide both sides by 3 \n\nx = 1

-9x + 7 = 3x + 19\n\nSubtract 7 on each side...\n\n-9x = 3x + 12\n\nSubtract 3 on each side...\n\n-12x = +12\n\nDivide by -12 on each side...\n\nx = -1

Multiply each term in the first () by each term in the second ():\n\n2x times 2x = 4x^2\n2x times 1 = 2x\n-3 times 2x = -6x\n-3 times 1 = -3\n\nThen combine 2x and -6x\nAnswer: 4x^2 - 4x - 3

9x-(-2x) = 5x+4x-{2(x-10+3+7)}(-1) = 5x +2x-11x+22x-5x-x+x(-1)\n\n= 11x

3|(2x-1)/5| + 3 = 1?\nThats impossible. |anything| >= 0, so the LHS is >= 3. Did you mean something else?

x(x^2 -9)= x (x-3)(x+3)

this would multiply out to be 4x^2-9\n\nif you let the expression be equal to 0, then x would be positive or negative 3/2 because either (2x+3) = 0 or (2x-3) = 0, and just solve for x

first multiple everythingby x, then simplify and solve:\n\n1/x-2 = 3/x+3 =>\n\nx/x - 2x = 3x/x +3x =>\n\n1 - 2x = 3 + 3x =>\n\n-2  = x

x-4x+9+3(-2+1)+2=0\nx-4x+9+3*(-1)+2=0\nx-4x+9-3+2=0\n-3x+8=0\n-3x=-8\nx=8/3\nThis is if the equation was x-4x+9=-3(-2+1)-2, but if it was just -4x+9 = -3(-2+1)-2 than the answer is 2 (-4x=-8    x=2).

x^2-6x+9 = (x-3)(x-3)\nx^2-9 = (x-3)(x+3)\n\nMultiple everything by (x-3)(x-3)(x+3)\n\n(x+3)(x+3) - (x+2)(x-3) - 5(x-3)(x+3)\n\nx^2+6x+9 - (x^2-x-6) - (5x^2-45)\n\nx^2+6x+9-x^2+x+6-5x^2+45\n\n-5x^2 + 7x + 60
