Answer 1

Answer:

The given equation is 3x+y=11 and x−y=1

Now, let us find atleast two solutions of each of the above equations, as shown in the following tables.

Table for 3x+y=11  or y=3x−11

Now, table for x−y=1 or y=x−1

Here, the lines intersecting at point C (3, 2)

The coordinates of the

vertices of △CBE are  C (3, 2), B(0, 11)

and E(0, -1).

Area  = $$\frac{1} {2}

\times base \times height$$
