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)
