Answer:
x=7
7-4=3
7+2=9
Step-by-step explanation:
Triangle ABE and Triangle CDB are similar
4*3=12
ABE is 3 times bigger than CDB
3(x-4)=x+2
3x-12=x+2
2x-12=2
2x=14
x=7
7-4=3
7+2=9

Good evening ,
_______________
2(7) + 5(1) + 3(-3) = 10
3(7) - (1) + 4(-3) = 8
5(7) - 2(1) + 7(-3) = 12
Then (7,1,-3) is a solution to system

Answer:
Solution is invalid
Step-by-step explanation:
Let the time when they will have the same water content be x hours
At x hours;
For the first tank, the content will be;
50 + 10x
For the second;
29 + 3x
Equating both, will give us x
29 + 3x = 50 + 10x
We will get x as a negative number here
Since number of hours can not be negative, the solution is invalid
