Look for the GCF. 7, 14 and 21 all have 7 as a common factor. Divide that out.
7x divided by 7 = x
21 divided by 7 = 3
14y divided by 7 = 2y
7x + 21 + 14y = 7(x + 3 + 2y)

What is the answer for the equation 7x-14y -56?
Without an equality sign the given terms of an expression can't be classed as an equation and so therefore an answer is not possible.
What is 3x-3 equals 7x 21?
If: 3x-3 = 7x+21 Then: x = -6
How do you factor x2 plus 7x plus 6?
x2 + 7x + 6 = (x + 6) (x + 1)
How do you factor 12x squared -7x -12?
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored
How do you factor x2 - 7x 12?
If you mean: x squared -7x +12 then it is (x-3)(x-4) when factored
How do you factor 7x-14y?
7(x - 2y)
How do you factor 7x plus 14y?
It is: 7(x+2y)
What is the greatest common factor of 7x and 21?
The GCF is 7.
Solve by substitution x plus 5y equal 10 and 7x minus 14y equal 49?
set it up as x+5y=10 and 7x-14y=49 on top of each other and then multiply x+5y=10 by -7. That gives you -7x-35y=-70. cross out the X's and add the Y's. -21y=21 divide and get -1=y then sub. for x and solve. X=15 and X=5

What is the greatest common factor of 7x and 14xy?
Since 7x is a factor of 14xy, it is automatically the GCF.
How do you factor 49x2 -64?
(7x + 8)(7x - 8)
Factor y2-14y plus 24?
(y-12)(y-2)
How do you factor 3y2 - 14y plus 8?
(3y - 2)(y - 4)
What is the answer for 12x minus 4 equal 7x minus 21?
12x - 4 = 7x - 21 12x -7x = -21 + 4 5x = -17 x = -3.4
Factor 49x squared minus 7x minus 72?
(7x + 8)(7x - 9)
What is 3x-3 equals 7x 21?
If: 3x-3 = 7x+21 Then: x = -6
