Answer 2

Answer:

By solving these linear equations 2x - y = 5 and x + 3y = 6, the values are x = 3 and y = 1.

Step-by-step explanation:

Given,

The linear equations are 2x - y = 5 and x + 3y = 6.

2x - y = 5       -- (i)

x + 3y = 6       -- (ii)

Solving by using elimination method

Multiplying equation (ii) by 2, we get

2x + 6y = 12      -- (iii)

Now, (iii) and (i), we get

6y + y  = 12 - 5

⇒ 7y = 7

⇒ y = 1

and,

x + 3(1) = 6

⇒ x = 6 - 3

⇒ x = 3

Hence, by solving these linear equations 2x - y = 5 and x + 3y = 6, the values are x = 3 and y = 1.
