Gwar [14]

Answer: x = 4

Step-by-step explanation:

x + y = 5

y = 5 - x

3x - 3y = 9

=> 3x - 3(5-x) = 9

=> 3x - 15 + 3x = 9

=> 6x = 24

2e - 3f = 4

Varvara68 [4.7K]

Answer:

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

Step-by-step explanation:

The steps are :

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

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

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

$2f = - 4$

$f = - 4 \div 2$

$f = - 2$

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

$2e - 3( - 2) = 4$

$2e + 6 = 4$

$2e = 4 - 6$

$2e = - 2$

$e = - 2 \div 2$

$e = - 1$
