Fist choice.
Answer:
The two numbers are 2928 and 1878
Step-by-step explanation:
Given this information, we can set up two equations:
x + y = 4806
x - y = 1050
We can solve these simultaneous equations by elimination, which means we can either add or subtract the two equations to solve one of the variables.
In this case, adding the equations together will eliminate y so we can solve for x (remember that y + - y is the same as y - y):
x + y = 4806
+ x - y = 1050
____________
2x = 5856
This can then be simplified to x = 2928 (by dividing by 2)
Now we know x, we can substitute this value into any equation to find y:
2928 + y = 4806 so y = 4806 - 2928 which is 1878.
The two numbers are 2928 and 1878.
Hope this helps!
