If the two equations are related, and if the second equation is correct, then the first equation is wrong.\nIf 3x=2(x-4), then 3x-2(x-4)=0\nOn the other hand, if the two equations are not related, then x could be different in each, and therefore both could be correct.

for the last one, if you're aking (x-3)^2= 36....\nsquare root both sides to get (x-3) = 6 and -(x-3)= 6\nthen for the (x-3) you add 3 to both sides to get x=9\nfor the -(x-3)=6 you distribute and get -x+3=6, the answer it x=-3\n\nso...... x= 9 or -3

You have got it right.\nthe answer is\n\nf(x) = 3x

4x = x - 12\nThe word "is" is always the equal sign.\nSubtract x from both sides\nyou get 3x = -12\ndivide by three on both sides\nThe answer is -4.\n\n\nhahahaha\n(at GaryPopkin)

(x2)-3 (x-2) over (x2) -4?\nIs this what you mean?\n(x^2)^(-3)*x^(-2)/(x^2)^(-4)\n= x^(-6)*x^(-2)/x^(-8)\n= x^(-6-2-(-8))\n= x^(-8+8)\n= x^0 \n= 1

2(x -1) + 3 = X – 3(x + 1)\n2x-2 +3 = x - 3x-3\n2x + 1 = -2x -3 \n2x + 2x = -3 - 1\n4x = -4 \n4x/4 = -4/4 \nx = -1 \n\nTo check your answer plug -1 in the place of x in the main equation:\n2(-1-1) + 3 = -1-3(-1+1)\n-4 + 3 = -1 \n-1 = -1\nThus x = -1 is the correct answer.

Very ingenious to have a "That's Me" account. You can give yourself ten points over and over.\n\nfor x = -3, x^2 = 9 and 3x = -9. Result = 0\nfor x = -2, x^2 = 4 and 3x = -6. Result = -2\nfor x = -1, x^2 = 1 and 3x = -3. Result = -2\nfor x = 0, x^2 = 0 and 3x = 0. Result = 0\nfor x = 1, x^2 = 1 and 3x = 3. Result = 3\n\nOnly your zero value is correct.\n\nThis is an upward-opening parabola with its minimum point at \n\nx = -1.5\n\nIt crosses the x-axis at (-3, 0) and (0, 0). Obviously, it crosses the y-axis at (0, 0) also.

It's false.\n\nYou have to use order of operations. You do the stuff in the parenthesis first:\n\n(3-3) - 3 = 3- (3-3)\n(0)-3=3-(0)\n\nSo you get:\n-3=3\n\nSince -3 isn't equal to 3, it's not true.
