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 10 equals 59.
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
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
49 plus 10 equals 59.
49 plus 7 equals 56.
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

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