Question

Given that

Answer 1

Answer:

y = - 49

Step-by-step explanation:

Given

7x - 2y = 35 ← substitute x = - 9 into the equation

7(- 9) - 2y = 35, that is

- 63 - 2y = 35 ( add 63 to both sides )

- 2y = 98 ( divide both sides by - 2 )

y = - 49

Answer 2

Answer:

$\boxed{y = -49}$

Step-by-step explanation:

=> $7x-2y = 25$

Given that x = -9

=> $7(-9)-2y = 35$

=> $-63 -2y = 35$

Adding 63 to both sides

=> $-2y = 35+63$

=> $-2y = 98$

Dividing both sides by -2

=> $y = 98/-2$

=> $y = -49$
