=3x+7
(-3x - 1)(3x - 7)
38*4 + 3 + 7 - 3x = 162 - 3x
3x+7=4x 7=4x-3x 7=x
5x+7
13x + 7
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
4x plus 7 plus 3x equals 19 plus xx = 2
d/dx 2x2+3x+7=4x+3
In the equation 3x plus 7 equals 13, x is equal to 2.
4x plus 7
3x plus 10x - 7With out knowing what ' x ' actually is.. it will reduce down to.3x + 10 x - 7=13x - 7
