4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
6x+11=92-3x +3x +3x 9x+11=92 -11 -11 9x=81 divide by 9 x=9
x2 + 6x - 2 = 0 x2 + 6x + 9 = 13 (x + 3)2 = 13 x + 3 = ± √13 x = -3 ± √13
6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8
x=-9 15 + x = 6x + 60 x = 6x + 45 -5x = 45 x = -9 15 + (-9) = (6 * (-9)) + 60 15 - 9 = -54 + 60 6 = 60 - 54 6 = 6 There is no answer because, 15+x=6x+60 -15 -15 x=6x+45 Which is imposible because "x" can't equal itself times six plus forty-five.
Put in function, Y = mX + C, form. 6X + 3Y = - 9 3Y = - 6X - 9 Y = - 2X - 3 -------------------- m(slope) = - 2 ----------------------
-6x + y = 9 (+6x) -> y = 6x + 9
-6x+9 = 45 -6x = 45-9 -6x = 36 x = -6
16x+9 without the rest of the equation, what this equals, I can't solve
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
2x+6x=-9 => 8x=-9=> x=-8/9
5x + x - 6x + 2x = 2x
-324
the answer is -3x = 0
0.2x + 6x - 1 = -9 6.2x = -8 x = -1.2903225806451612903225806451613
If: x-9 = 6x+7 then x works out as -3.2
