42x
It is: 42x+30x^2
It means negative 42 times a certain number. x is a variable, you have to find x. Ex. if x is 1 then it would be -42 Multiplied by 1, which is -42.
7x = 42 Divide both sides by '7'. Hence x = 42/7 x = 6 The answer!!!!!
why don`t you try a calculator buy one if you don`t have one.
If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13
126 ._.
You said that 42x - 3 + 7 = 8x + 5 .Combine the like terms on the left side (the -3 and the +7):42x + 4 = 8x + 5Subtract 4 from each side:42x = 8x + 1Subtract 8x from each side:34x = 1Divide each side by 34:x = 1/34The solution set is: {34}
(-7x + 3)(-7x +3)
if x-42x-8=0 x=-5.12500
y-42x = 24 >> Add 42x to both sides << y=24+42x >> Subtract 24 from both sides << y-24=42x >> Divine both sides by 42 << x=(y-24)/42
-1/19=x
(6x3) + (7x3) = 18 + 21 = 39
−39x−6
5x - 42x + 5 = - 37 x +5
42x+35x-35x=42x it's leave 85 so it's change into a negative 42x-85 is the answer
(x - 2)(7x + 15)
