12x - 16y = 8\n9x - 12y = 6\n\n12x - 16y = 8\n-16y = -12x + 8\ny = (3/4)x - (1/2)\n\n9x - 12y = 6\n-12y = -9x + 6\ny = (3/4)x - (1/2)\n\nANS : 3.) (t,(3/4)t - (1/2))\n\nThats if i understand you correctly.

You know that\n              1)3x+4y=12y\n              2)-2x+10=12y\nSo you can substitute 3x+4y for 12y in equation 2. Hence:\n              3)3x+4y=-2x+10\n                   5x=10-4y\n                    x=2-4y/5\nSubstitute this value for x into equation 1 and it becomes:\n              1)8y/5+6=12y\n                     y=15/26\nPlug this back into 3 and you get\n              3)x=2-(4/5)*(15/26)\n                x=20/13\nTherefore the answer to the system is (x,y)=(20/13,15/26)

Usually these types of problems would have -4x where you have -4.  Assuming that's the case...\n\nMultiply the top row by 4.  That comes out 4x + 12y = 68\n\nAdd this to the bottom row.  That is 0x + 14y = 84\n\nor just 14y = 84\n\nDivide both sides by 14 and get y = 6\n\nPlug this in to either equation to get x:\nx + 3(6) = 17\nx + 18 = 17\nx = -1\n\nCheck in other equation: -4(-1) + 2(6) = 16\n4 + 12 = 16 check\n\nHope that helps

a)\n4x + 4y = -12\n-2x + 3y = 14\n\nDouble the second equation and add:\n4x + 4y = -12\n-4x + 6y = 28\n10y = 16\ny = 16/10\ny = 8/5\n\nThen solve for x:\nx + (8/5) = -3\nx = -3 - 8/5\nx = -4 3/5\n\nb) \n3x + 2y = 5\n2x - 3y = 3\n\nMultiply the top by 2 and the bottom by 3, then subtract:\n6x + 4y = 10\n6x - 9y = 9\n13y = 1\ny = 1/13\n\nThen solve for x:\n3x + 2(1/13) = 5\n3x + 2/13 = 5\n3x = 63/13\nx = 21/13\nx = 1 8/13

you do not get specific values, there are infinite number of solutions for each equations\n\n2x + y = 9, y= -2x + 9\n\n-x - y = - 8, y=-x+8\n\n- 3x + 4y = 2, y = 3x/4 - 1/2\n\n- 2x - y = - 3, y= -2x +3\n`

4x +y = 16   ;2x + 3y = 24      Multiply the 2nd with -2, that gives -4x -6y = -48    Add the two:   0x - 5y = -32  \nDivision by -5 gives  y = 6,4\nInsert this value into the first equation:   4x + 6,4 = 16\n4x = 9,6 ;    x = 2,4\n\nNumber 2 is even easier:\nMultiply the first equation by 2 and add the equations.\n24x + 2y = 50    plus   8x - 2y = 14  gives  32x = 64; x = 2\nYou can now choose:  24 + y = 25  or  16 - 2y = 14\n(That you get when you replace in the original equations \nx by 2)  Anyhow you'll find   y = 1

Yes and No at the same time.  \n\ns = 0\n6(8s-3) = 48s - 18\n48s - 18 = 48s - 18\n(48)(0) - 18 = (48)(0) - 18\n-18 = -18\n\nor\ns = 1\n6(8s-3) = 48s - 18\n48s - 18 = 48s - 18\n(48)(1) - 18 = (48)(1) - 18\n48 - 18 = 48 - 18\n30 = 30\n\nActually all real numbers will work becuase the equations are equal.

the value you need is 12*12-4*9*16 = 144-576 = -432\n\nBecause it is negative, the equation has NO real solutions.
