You can identify the lines and their colour either by 1. the y-intercepts. First equation has a y-intercept of 3 and second has a y-intercept of 2. So first equation is blue, and second is red. 2. the slopes First equation has a negative slope (so blue), and second has a positive slope (so red).
Now work on each of the equations. 1. first equation (blue) If we put x=0, we end up with the equation y≤3, the ≤ sign indicates that the region is BELOW the BLUE line. 2. second equation (red). If we put x=0, we end up with the equation y>2, the > sign indicates that the region is ABOVE the RED line AND the red line should be dotted (full line if ≥).
So at the point, it won't be too hard to find the correct region.
To confirm, take a point definitely in the region, such as (-6,0) and substitute in each equation to make sure that both conditions are satisfied.
I havnt done that in a while but I think you do x+105=x+95 then you add your like terms which would turn into 10=2x then you divide 10 divided by 2 which is 5, SO YOUR ANSWER IS (I think) 5x
