2x+9 = 49-3x
2x+3x = 49-9
5x = 40
x = 8
3x-5+2x=-49 is the same as 5x=-44 or x=-44/5
It is an equation and the value of x is 6
5x+49 = 8x+13 49-13 = 8x-5x 36 = 3x x = 12
4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
49 plus 7 equals 56.
3x-5+2x=-49 is the same as 5x=-44 or x=-44/5

4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
44
Remember in algebra any operation you do to one side of the equaution and also to the other side does not affect the eqaution 8x + 7 = 2x + 49 subtract 2x from both sides 6x + 7 = 49 subtract 7 from both sides 6x = 42 divide both sides by 6 x = 7
49 plus 7 equals 56.
49 plus 10 equals 59.

2x2 + 21x + 49 = 2x2 +14x +7x + 49 = 2x(x + 7) + 7(x + 7) = (2x + 7)(x + 7)
