Solve for y Please help I need a tip
Gwar [14]

Answer:

y = 4

Step-by-step explanation:

Step 1: Write equation

9/4y - 12 = 1/4y - 4

Step 2: Solve for <em>y</em>

  1. Subtract 1/4y on both sides: 8/4y - 12 = -4
  2. Simplify: 2y - 12 = -4
  3. Add 12 to both sides: 2y = 8
  4. Divide both sides by 2: y = 4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

9/4(4) - 12 = 1/4(4) - 4

9 - 12 = 1 - 4

-3 = -3
