(Q.10). Solve the following systems of equation: 2x – y = 4; 4x – 2y = 6

2x – y = 4

y = 2 - 4

2x – y = 4
x y = 2x - 4 (x,y)
0 - (0,-)
2 (2,)
1 - (1,-)
-1 - (-1,-)

4x – 2y = 6

⇒ 2y = 4x –

⇒ y = 2x –

4x – 2y = 6
x y = 2x - 3 (x,y)
0 - (0,-)
2 (2,)
1 - (1,-)
3 (3,)

These two are lines.

∴ The pair of equations has no solution.
