Math Problem Statement

Solve for y: (9/4)y - 12 = (1/4)y - 4

Solution

The equation given in the image is:

94y12=14y4\frac{9}{4}y - 12 = \frac{1}{4}y - 4

Step-by-step solution:

  1. Move all terms involving yy to one side: Subtract 14y\frac{1}{4}y from both sides:

    94y14y12=4\frac{9}{4}y - \frac{1}{4}y - 12 = -4

    Simplify the left-hand side:

    84y12=4\frac{8}{4}y - 12 = -4

    This simplifies to:

    2y12=42y - 12 = -4

  2. Move constant terms to the other side: Add 12 to both sides:

    2y=4+122y = -4 + 12

    Simplify:

    2y=82y = 8

  3. Solve for yy: Divide both sides by 2:

    y=82y = \frac{8}{2}

    y=4y = 4

Final Answer:

y=4y = 4
