What is the value of x and y in 3x-y equals 21?
-18
-3x equals -21 plus 4x?
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
What is 9x squared minus 3x?
That factors to 3x(3x - 1)
What is 3x-3 equals 7x 21?
If: 3x-3 = 7x+21 Then: x = -6
What is the equation 3x 125-21?
I have to assume you mean 3x=125-21. Therefore 3x is 104. x = 104/3 = 34.667
How do you factor -9x3-3x2 plus 3x plus 1?
If that's -9x^3 - 3x^2 + 3x + 1, that factors to (1 - 3x^2)(1 + 3x)
How do you solve 3x minus 6 equals 21?
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
How do you factorise- x2-3x 2 equals?
assuming x*2-3x+2:factors of -3:-1,3 --> sum: 21,-3 --> sum: -2(x-1)(x+3)
What is 8x-4equlals 3x plus 21?
If: 8x-4 = 3x+21 Then: 8x-3x = 21+4 => 5x = 25 => x = 25/5 Therefore: x = 5
What is the slope of -7y plus 21 equals 3x?
-7y + 21 = 3x Add '7y' to both sides 21 = 3x + 7y Subtract '3x' from both sides 21 - 3x = 7y 'Swop around'. 7y = -3x + 21 Divide both sides by '7' y = -(3/7)x + 3 The slope of a straight line is the coefficient of 'x' In this case it is ' -3/7'.
What are the factors of 9x2 3x-2?
If you mean: 9x2+3x-2 = (3x+2)(3x-1) when factored
5x plus 7 equals 3x-21?
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
