Answer 1

Answer:

The solution of the system of equation are (10,15).

Step-by-step explanation:

The given two linear two variable equations are  

- x - 2y = - 40 ........ (1) and  

x + 4y = 70 .......... (2)

Now,adding thoes two equations (1) and (2) we get,

- 2y + 4y = - 40 + 70

⇒ 2y = 30

⇒ y = 15.

Now, putting y = 15 in the equation (2), we get,

x = 70 - 4y = 70 - 4(15) = 10

Therefore, the solution of the system of equation are (10,15). (Answer)
