The given quadratic expression can not be factorized because its discriminant is less than zero.
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
5x+7
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
8x + 7
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
3x - 7 = 5x + 13-2x = 20x = -10
If: 3x-7 = 5x+13 Then: x = -10
It is 5x - 4
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x
= 5x plus 7.
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
