Question

6 Solve the following pair of linear equation by
Substitution Method
Elimination Method
2x+y=14
x -y=6​

Answer 1

Answer:

2x+y=14----- (1)

x - y=6​----- (2)

Adding both the equations, we get

3x = 20

$x = \frac{20}{3}$

From (2) equation-----

x - y=6

$\frac{20}{3} - y =6$

$y = \frac{20}{3} - 6$

$y = \frac{20-18}{3}$

$y = \frac{2}{3}$
