Answer 1

Step-by-step explanation:

by subtracting method

Answer 2

Answer:

1. x-3y=10 first excavation
2. x-7y=-30 second excavation
3. that first excavation -second excavation
4. then. y=10get
5. y value put in first excavation we got x=40
6. so that x=40 and y=10 acoding to first and second excavation
