Question

Solve the equation for y: 4x + 3y = -12
A. y = -12 - 4/3 x
B. y = -4 - 4/3 x
C. y = -12 + 4x
D. y = -4 + 4x

Answer 1

4x + 3y = -12

=> 3y = -12 - 4x

=> y = -12 -4/3 x

Therefore, (A) y = -12 - 4/3 x is the correct option.

Answer 2

4x + 3y = -12
\[ 4x \color{red}{-4x}+ 3y = -12 \color{red}{-4x} \\ \\ 3y=-12-4x \]
Now divide both sides by 3

Answer 3

ok. So y=-12-4/3x

Answer 4
