★Question

• Solve the following system of linear equations by substitution method:

• 2x – y = 2

• x + 3y =15

Solution

Here, 2x – y = 2

• ⟹ y = 2x – 2_____(I)

★Now

• ⟹ x + 3y = 15____(ii)

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

• x + 6x – 6 = 15

• ⟹ 7x = 21

• ⟹ x = 3_______(I)

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

• y = 2 × 3 – 2 = 4

• ∴ x = 3 and y = 4

★Hence x = 3 and y = 4

IDk I'm getting some strange feelings for the above answer as if I hve only answered it .
