Answer 1

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)
