X+y=5 2x-y=4 solve garpa​

x = 3, y = 2

Step-by-step explanation:

x + y = 5

x = 5 - y

2x - y = 4

2(5 - y) - y = 4

10 - 2y - y = 4

10 - 3y = 4

3y = 10 - 4

3y = 6

==> y = 2

x = 5 - y

x = 5 - 2

==> x = 3

x=3. y=2

Explanation

x+y=5 2x-y=4

x=5-y

2(5-y) - y =4

10-2y-y=4

-2y - y = 4 - 10

-3y = -6

y = 2

x = 5-y

x=5-2

x=3

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
