math Solution:3x -4y=-6 and x + 4y+16?

Well you must have two equations! If you wanted to say x+4y=16 then just add the two and you'll fing x (4x=10) and then find y from one of them.

6x - 2y = 8 dividing both sides by 2 we get => 3x - y = 4 -----(1)\n3x + 7y = - 4 -----(2)\n(1) - (2) => 3x - y - 3x - 7y = 4 - (-4)\n-8y = 8 and y= -1\nso x = 1

6x(x-3y)-3(6x^2-xy) = 6x^2-18xy-18x^2+3xy=-12x^2-15xy ans.

ok sorry, i'll work it out this time\n\n3x-6y=-30\n-8x+20y=104\n\n(8)(3x-6y)=-30(8)\n(3)(-8x+20y=104(3)\n\n24x-48y=-240\n-24x+60y=312\n\n12y=72\n\ny=6\n\n3x-6(6)=-30\n\n3x-36=-30\n\n3x=6\n\nx=2\n\ndoes that help?

cross-multiply : 4/x+3 = 6/4-x is the same as 4(4-x)=6(x+3), so 16-4x = 6x +18 :\n16-18 = 6x + 4x\n-2 = 10x\n-2/10 = 10x/10\n-0.2=x ( which is the same as x = -1/5 not  -1.5)

1. Distribute the 4 on the left of the = sign\n   4(4x) + 4(1)\n2. Distrube the 3 on the right of the = sign\n   3(4x) - 3(5)\n3. Combine like terms and solve\n\n16x + 4 = 12x - 15\nsubtract 4 from each side, then subtract 12x from each side.  Divide each side by the number in front of x to find what x equals to.

here is how you go about it\n3x - 6 + 3x - 4 = 17\n6x - 10 = 17\n6x = 17 + 10\n6x = 27\ntherefore,\nx = 27/6\n  = 4.5\n\nyou are right!!

1) x = y\nSubstituting:\n4x - 3x = -3\nx = -3\ny = -3\n\n2) 3x + 2y = 6\nx = 2y - 6\nSubstituting:\n3(2y - 6) + 2y = 6\n6y - 18 + 2y = 6\n8y = 24\ny = 3\nx = 2(3) - 6\nx = 0\ny = 3\n\n3) 2x - 6y = 2\n-3x + 9y = -3\nIf you divide the top by 2 and the bottom by -3 you get:\nx - 3y = 1\nx - 3y = 1\n\nThese are equivalent, so you can't determine a single solution.\n\nThe best you can do is simplify the equation to get a formula for y given x:\n3y = x - 1\ny = (1/3)x + (-1/3)\nBecause you can't isolate a single variable, you essentially have one equation and two unknowns.  The solutions will lie along the line with a slope of 1/3 and a y-intercept of -1/3.
