-2x/3y times -9x(squared)/2 = ?
609702
hard to type it out without a notational keyboard\n\n-2x/3y  * -9x(2)/2\n\nyou can use the diagonal to divide out extra numbers\nso eliminate the 2 and the 3\n\n-x/y * -3x(2)\n\nthen multiple the top and the bottom separately\n\n-x*-3x(2)\n_________\n  y * 1\n\ntwo negatives multipled make a positive so the result is\n3x(cubed) divided by y\n\n3x(3)/y

2x - 8y = 3\nadd 8y to both sides and subtract 3 from both sides\n2x - 3 = 8y\ndivide both sides by 8\n(x/4) - (3/8) = y\n\nANSWER\n(x/4) - (3/8) = y

Just divide through by 3 to get the y alone\n\n3y = 2x + 3\n\n3y /3 = 2x/3 + 3/3\ny = (2/3)x + 1

y = 3x²\n\nS(x, y) = (3x, 2y)\n\nSo y = 3x² →2y = 3(3x)²\n\nie y = 27x²/2

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

2x^2 - 2y^2 = 2(x^2 -y^2) = 2(x-y)(x+y)\n-2x^2 + 2xy = -2x(x-y)\nx^2 + xy = x(x+y)\n2(x-y)(x+y)/[-2x(x -y)]/[x(x+y)]\n= 2(x-y)(x+y)/[-2x(x-y)(x)(x+y)]\n= -1/x^2

assuming this is your question\n? / (5xy-9x) = (3+25y) / (9-5y)\n? = -x * (9-5y) * (3+25y) / (9-5y)\n? = -3x -25xy\n\nnow pay up

Easy!\n\n2x+2y=2 \n3x-y=1\n\nTake the second equation and isolate the single "y":\n\n3x - y = 1 becomes 3x - 1 = y (without going into how)\n\nSubstitute "3x - 1" in the first equation so it reads:\n\n2x+2(3x - 1)=2\n\nSimplify:\n\n2x + 6x - 2 = 2\n8x - 2 = 2\n8x = 4\nx = 1/2\n\nEarlier, we saw that y = 3x - 1, so:\n\ny = 3(1/2) - 1\ny = 3/2 - 1\ny = 1/2\n\nThere may be another way (less involved) that I've forgotten, but you can check each of those values for x and y in both equations to make sure they work.
