Question

1. solve for y when x = 2 in the equation 2x - 3y = 7.

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

Explanation:

Step1: Substitute x=2 into equation

$2(2) - 3y = 7$

Step2: Simplify left-hand side

$4 - 3y = 7$

Step3: Isolate the y-term

$-3y = 7 - 4$
$-3y = 3$

Step4: Solve for y

$y = \frac{3}{-3}$
$y = -1$

Answer:

a. -1
