Question

1. solve for ( y ) when ( x = 0 ) in the equation ( 3x - 9y = 27 ).

a. ( -3 )
b. ( 3 )
c. ( 0 )
d. ( 9 )

Explanation:

Step1: Substitute $x=0$ into equation

$3(0) - 9y = 27$

Step2: Simplify left-hand side

$0 - 9y = 27$
$-9y = 27$

Step3: Solve for $y$

$y = \frac{27}{-9}$
$y = -3$

Answer:

a. $-3$
