3(y – 5) + 2 = 5<br> A. y = 4<br> B. y = 7<br> C. y = –4<br> D. y = 6
ser-zykov [4K]

Answer:

y = 6

Step-by-step explanation:

Step 1: Write equation

3(y - 5) + 2 = 5

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

  1. Distribute 3: 3y - 15 + 2 = 5
  2. Combine like terms: 3y - 13 = 5
  3. Add 13 to both sides: 3y = 18
  4. Divide both sides by 3: y = 6

Step 3: Check

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

3(6 - 5) + 2 = 5

3(1) + 2 = 5

3 + 2 = 5

5 = 5
