Answer:
Factorise out x and y terms:
Answer:
1-5
Step-by-step explanation:
5 - 1 = 4
Answer:
the solution to the equations is :-
(4,3)
Step-by-step explanation:
here's the solution :-
=》x + 2y = 10
=》x = 10 - 2y
now, plugging the value of x in other equation :-
=》9x - 2y = 30
=》9 × (10 - 2y) - 2y = 30
=》90 - 18y -2y = 30
=》-20y = 30 - 90
=》y = -60 ÷ -20
=》y = 3
now, plugging the value of y in first equation,
=》x = 10 - 2y
=》x = 10 - (2×3)
=》x = 10 - 6
=》x = 4
so, the solution of the system is (4,3)
The answer is a). 3 sides multiply the numbers to get your product
