Question

. The solution of the equations given below are: x-y = 2 and 2/ x + y = 1/5 x = 4, y = 2 x = 5, y = 3 x = 6, y = 4 x = 7, y = 5

Answer 1

Answer:

x = 6 , y = 4

Step-by-step explanation:

x - y =    2   L1

2/(x + y) = 1/5   L2

x - y = 2

x = 2 + y   Remplace in L2

2/(x + y) = 1/5

2/(2 + y + y) = 1/5

2/(2+2y) = 1/5

2 = 1/5(2+2y)

2 = 2/5 + 2/5y

-2/5y = 2/5 - 2

-2/5 y = -8/5

y = -5/2 * -8/5

y = 8/2

y = 4

x - y = 2

x = 2 + y

x = 2 + 4

x = 6
