Question

1. solve for ( y ) when ( x = 1 ) in the equation ( 4x - 2y = 8 ).

a. ( -2 )
b. ( 2 )
c. ( 1 )
d. ( 0 )

Explanation:

Step1: Substitute x=1 into equation

$4(1) - 2y = 8$

Step2: Simplify left-hand side

$4 - 2y = 8$

Step3: Isolate the y-term

$-2y = 8 - 4$
$-2y = 4$

Step4: Solve for y

$y = \frac{4}{-2} = -2$

Answer:

a. -2
