Question

Given that 7 x − 2 y = 35 Find y when x = − 9

Answer 1

Answer:

$\boxed{y = -49}$

Step-by-step explanation:

=> $7x-2y = 35$

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

=> $y = -49$

Answer 2

so x = minus 9

then

7 × (-9) - 2y = 35

-63 - 2y = 35

-2y = 35 plus 63

-2y = 98

- y = 49

y = -49
