Put the left side coefficients into matrix [A],\n[6 2]\n[5 6]\nand the right side values into matrix [B]\n[-16]\n[..4]\nthen tell the calculator to multiply [A] inverse * [B]\nthe result is the solution matrix\n[x]\n[y]\n\nnote, the inverse key looks like x^-1.  \n\nsolve the second system the same way.  coefficient matrix will be 3x3, answer matrix 3x1.

You use the coefficients and the answers to get a 2X3 matrix:\n1 1 8\n1-1 4\n\nAdd row 1 to row 2 to get a new row 2 with a zero in it:\n\n1 1 8\n2 0 12\n\nDivide row 2 by 2 to get a 1 in it\n\n1 1 8\n1 0 6\n\nMultiply row 2 by -1 and add it to row 1 to get a new row 1:\n\n0 1 2\n1 0 6\n\nSwitch the rows:\n\n1 0 6\n0 1 2\n\nSo x is 6 and y is 2\n\nCheck by plugging into the original equations

Yeah, make them graphable on your calc.\n\ny = 4-x\ny = 2x-2\n\nIf you want to solve, just set 4-x and 2x-2 equal to each other (since y must also be equal in both equations)\n\n4-x=2x-2\n3x=6\nx=2\n\n\n2+y=4\ny=2\n\nTheir intersection is (2,2)\n\nThe y-intercept of the first is 4, and the second is 2.\nThe slope for the first is -1, and the second is 2.\nThe x-intercept of the first is 4, and the second is 1.

hmm im not quite in college yet, but i hope to be help.\ndo you know the values for f, h, v, and a?\nif you do, id substitute it in.\nthen square both sides. \nand then solve.

y = ax² + bx + c\n\nWhen x = 2 y = 30 so 4a + 2b + c = 30 ...... (1)\nWhen x = 3 y = 15 so 9a + 3b + c = 15 ...... (2)\nWhen x = 4 y = 6 so 16a + 4b + c = 6 ........ (3)\n\n(2) - (1) 5a + b = -15 ....... (4)\n(3) - (2) 7a + b = -9 ......... (5)\n(5) - (4) 2a = 6\na = 3 so b = - 30 and c = 78\n\nie y = 3x² - 30x + 78

you would take the 2x-4y=3 and solve for a variable, such as x=(3-4y)/3   you now have what x equals and you sub that into the other equation so you now have 2[(3-4y)/3]-3y=0 and you should be able to solve that equation
