7 & 11 have no common factor: both are prime.
minus 4 plus 9 = 5, so 5x
Set up the equation and solve: -27 = 8x - 5x (next simplify by subtracting 5x from 8x)) -27 = 3x (next divide both sides of the equation by 3) -27/3 = 3x/3 (next simplify and solve) -9 = x
5x^2 + 14x - 3x^2 - 9 = 2x^2 + 14x - 9
5x +50x
9(5x) = 45x simplified
6x - 9 - x = 6Combine like terms on the left side:5x - 9 = 6Add 9 to each side:5x = 15Divide each side by 5:x = 3By the time you simplify it, you've solved it.
7 & 11 have no common factor: both are prime.
5x - 4x = x
minus 4 plus 9 = 5, so 5x
Set up the equation and solve: -27 = 8x - 5x (next simplify by subtracting 5x from 8x)) -27 = 3x (next divide both sides of the equation by 3) -27/3 = 3x/3 (next simplify and solve) -9 = x
5x^2 + 14x - 3x^2 - 9 = 2x^2 + 14x - 9
5x +50x
you can't because it is not an equation but you can simplify it. The simplified version would be 5x times 9
2x plus 5x simplified is 7x.
