x + 5 < 4 or 2 - 7x < 16?

Solving for x in the first equation gives us...\n\nx + 5 - 5 < 4 - 5\nx < -1\n\nSolving for x in the second gives us...\n\n2 - 7x - 2 < 16 - 2\n-7x < 14\n---   ---   Here, don't forget to swap the sign\n -7    -7   since we are dividing by a negative.\nx > -2\n\nSo use that to find your solution set.  We know x must be less than -1 but greater than -2.  \n\nHope this is helpful.

7+13-4=16\n\ngotta subtract 4 since it is counted twice - both 7 and 13 include it.

x^2 - 8x + 16\n\n\nthe person above me said it is -x^2 but that is incorrect because -x * -x = x^2

since no one else will explain it, if u have 7a-5<9. then u have to add five to both sides to get rid of it on the left side. so that makes 7a<14. then to get a by it self, u have to divide both sides by 7. so u get a<2.

I'm not sure if the x is supposed to be the multiplication symbol or a variable.\n\nIf you mean 2*(4*2) or 2(4*2), the result is: 16\n\nIf it is the letter "x", the answer is:\n2x(4*2) = 2x(8) = 16x

simply subtract 7 from both sides. This leave you with\n\nx<_3

7x - 30 <19 \n\n7x - 30 + 30 < 19 + 30\n\n7x < 49\n\n7x/7 <  49 / 7\n\nx < 7\n\nThe answer is x < 7\n\nInsert th x value into the equation\n\n- - - - - - - - -\n\nCheck\n\n7x - 30 < 19\n\n7(7) - 30< 19\n\n49 - 30 < 19\n\n19 = 19\n\n- - - - -- - -s-

U could do y=-2x+5 or you could do y=-7x (I luv math)

9x+5/(x-4)+(-7x)/(x-4)\n=9x+5-7x/(x-4)\n=(2x+5)/(x-4)

4x + (x + 2) ....... 4x + 2 is 4 times a number plus 2 and it's incorrect

Yes it is\nX+7=11\n  -7    -7\nX=4
