Answer:

x=2, y=1

x=-2, y = -1

Step-by-step explanation:

x - 2y = 0

x = 2y

x² - y² = 3

(2y)² - y² = 3

3y² = 3

y² = 1

y = 1 or y = - 1

x = 2 or x = -2

2e - 3f = 4
Varvara68 [4.7K]

Answer:

The value of e is -1 and f is -2.

Step-by-step explanation:

The steps are :

2e - 3f = 4 -  -  - (1)

2e - 5f = 8 -  -  - (2)

2e - 3f - 2e - ( - 5f) = 4 - 8

2f =  - 4

f =  - 4 \div 2

f =  - 2

substitute \: f =  - 2  \: into \: (1)

2e - 3( - 2) = 4

2e + 6 =   4

2e = 4 - 6

2e =  - 2

e =  - 2 \div 2

e =  - 1
