Answer:
5,000,000 and 6,000,000
Step-by-step explanation:
5,000,000 and 6,000,000 is 11,000,000
or 5,000,000 and 5,000,000 is 10,000,000
and the 1 is in the ten millions place in the sum
Answer:
(-2, -4)
Step-by-step explanation:
Given:
The system of equations to solve is given as:

In order to solve this system of linear equations, we use substitution method.
In substitution method, we substitute the value of any one variable in the other equation.
So, we substitute the value of 'y' from first equation in the second equation.
This gives,

Dividing both sides by 3, we get:

Now, 
Therefore, the solution is (-2, -4)
