Answer:
(5, - 6 )
Step-by-step explanation:
Given the 2 equations
- 8x - 10y = 20 → (1)
- 8x - 6y = - 4 → (2)
Multiply (2) by - 1
8x + 6y = 4 → (3)
Add (1) and (3) term by term to eliminate the x- term, that is
- 4y = 24 ( divide both sides by - 4 )
y = - 6
Substitute y = - 6 into either of the 2 equations and solve for x
Substituting into (1)
- 8x - 10(- 6) = 20
- 8x + 60 = 20 ( subtract 60 from both sides )
- 8x = - 40 ( divide both sides by - 8 )
x = 5
solution is (5, - 6 )

Answer:
Sara studied longer.
She studied longer by 15 minutes.
Step-by-step explanation:
Sebastian:- 3:15 - 4:45p.m
Sara :- 4:30 - 6:15p.m
For how long did Sebastian study?
4:45
-3:15
1:30
Proof:
1:30
+3:15
4:45
Sebastian studied for an hour and 30 minutes.
For how long did Sara study?
6:15
-4:30
1:45
Proof:
6:15 to min=375
4:30 to min=270
375-270=105
105 min to hour=1:45
Hope this helps ;) ❤❤❤
