Question

solve graphically 2x-y=2 and x+3y=15​

Answer 1

Answer:

2

Step-by-step explanation:

2x-y=2

x+y=2+2

2x=4

x=4/2

=2

Answer 2

Answer:

Here, 2x – y = 2

⟹ y = 2x – 2

⟹ x + 3y = 15

Substituting the value of y from (i) in (ii), we get

x + 6x – 6 = 15

⟹ 7x = 21

⟹ x = 3

From (i), y = 2 × 3 – 2 = 4

∴ x = 3 and y = 4
