Question

Solve for y: 3x - 4y = 12​

Answer 1

3x-4y=12
4y=3x-12
y=(3x-12)/4
y=(3/4)x-3

Answer 2

Answer:

y = 3/4x -3

Step-by-step explanation:

$3x-4y=12$

Move 3x to the right and change its sign

$-4y = -3x+12$

Divide both sides of the equation by -4

$\frac{-4y}{-4} =\frac{-3x}{-4} + \frac{12}{-4} \\\\y = \frac{3}{4} x -3$
