3x+2 is because they never gave u an coefficient to put it in for x
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
3x + (-2 + 4x) = -2 + 7x
The sum of 3x plus 2 and -4 plus 3 is 3x+1 if the equation is (3x+2)+(-4+3). If they are two separate questions, 3x+2 remains as itself while -4+3=-1.
x = 7 and 2/3
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
