By means of graph verify that the point (1-1) is a solution of the equation 3x+2y-1=0   2x+y-1=0

Dear Student!

The given equation are 3x + 2y – 1 = 0 and 2x + y – 1 = 0.

Consider the equation 3x + 2y – 1 = 0.

3x + 2y – 1 = 0

⇒ 2y = 1 – 3x

Thus we have the following table,

Consider the equation 2x + y – 1 = 0

2x + y – 1 = 0

y = 1 – 2x

When x = 1, y = 1 – 2 × 1 = 1 – 2 = – 1

When x = 2, y = 1 – 2 × 2 = 1 – 4 = – 3

When x = –1, y = 1 – 2 × ( – 1) = 1 + 2 = 3

Thus, we have the following table,

The graph of the given linear equation is given as,

Thus, ( 1, –1) is the solution of the given equations.

Cheers!
