W  -width of the brand name TV, L - length of the brand name TV;
3/8 W = 12
W = 12 : 3/8 = 12 · 8/3 = 32 in
3/8 L = 24
L = 24 : 3/8 = 12 · 8/3 = 64 in
A ) 32 inches by 64 inches.

First we rewrite the system of equations:   y = x - 1  y = x - 3/2  we observe that the straight lines have the same slope, m = 1, therefore, the straight lines are parallel.  thus, the system has no solution (it is linearly dependent).  answer:   it has no solution, the lines do not intersect.
