Q. Which of the following is equivalent to 3x4y=6 3 x-4 y=6 ?\newline(A) y=67xy=-\frac{6}{7} x\newline(B) y=34x y=-\frac{3}{4} x \newline(C) y=43x+2 y=\frac{4}{3} x+2 \newline(D) y=34x32 y=\frac{3}{4} x-\frac{3}{2}
  1. Move 3x3x term: Isolate the variable yy in the equation 3x4y=63x-4y=6. To do this, we need to move the term 3x3x to the other side of the equation by subtracting 3x3x from both sides. 3x4y3x=63x3x - 4y - 3x = 6 - 3x This simplifies to: 4y=3x+6-4y = -3x + 6
  2. Divide by 4-4: Divide both sides of the equation by 4-4 to solve for yy.4y/4=(3x+6)/4-4y / -4 = (-3x + 6) / -4This simplifies to:y=(3/4)x(6/4)y = (3/4)x - (6/4)
  3. Simplify fraction: Simplify the fraction (64)(\frac{6}{4}).64\frac{6}{4} can be reduced to 32\frac{3}{2}. So the equation becomes: y=(34)x(32)y = (\frac{3}{4})x - (\frac{3}{2})
  4. Check options: Check the given options to see which one matches the simplified equation.\newlineThe correct option should be y=34x32y = \frac{3}{4}x - \frac{3}{2}.
