3(x+4) is the same as 3x+12 when the brackets are expanded out
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.
-3x+14 = -4 -3x = -4-14 -3x = -18 x = 6
4 + 8x
3x + 4 = 16 3x = 16 - 4 x = 12/3 x = 4
