solve it as fast as possible ​

Answer 1

Answer:

Hey mate! Here's your answer:

Explanation:

2x + y = 23

4x - y = 19

Adding both the equations,

6x = 42

x = 7.

4(7) - y = 19

28 - y = 19

-y = -9

y = 9.

x - 3y

7 - 3(9)

7 - 27 = -20.

5y - 2x

5(9) - 2(7)

45 - 14 = 31.

So x - 3y = -20 and 5y - 2x = 31.
