Answer:
I think it would be 5 sorry if I'm wrong
The equation is 3n - 5 1/2. 5 1/2 = 5.5
3n - 5.5
n could equal 1 so, 3 x 1 - 5.5 = -2.5
3n - 5 1/2 = -2.5
-1 > (x + 4) / 2....multiply both sides by 2, eliminating the 2 on the right
2 * -1 > x + 4
-2 > x + 4 ....subtract 4 from both sides
-2 - 4 > x
-6 > x or x < -6
graphed : open circle (because there is no equal sign)...on -6, shading to the left
2.
5x+6=3x+4
2x=-2
x= -1
3.
7n-29=4n+7
3n=36
n=12
