Answer:

y = 8

Step-by-step explanation:

Hello!

We can solve for y by isolating it.

<h3>Solve for y</h3>
  • 3y - 15 = y + 1
  • 3y - 15 - y = y +1 - y
  • 2y - 15 = 1
  • 2y - 15 + 15 = 1 + 15
  • 2y = 16
  • y = 16/2
  • y = 8

The value of y is 8.

<h3> 3y ➖15 = y ➕ 1</h3>

<em>We move all terms to the left:</em>

<h3>3y ➖ 15 ➖ (y ➕ 1) = 0</h3>

<em>We get rid of the parentheses.</em>

<h3>3y ➖ y ➖ 1 ➖ 15 = 0</h3>

<em>We add all the numbers and all the variables.</em>

<h3>2y ➖ 16 = 0</h3>

<em>We move all terms containing y to the left side, all other terms to the right side</em>

<h3>2y = 16</h3><h3>y = 16/2</h3><h3>y = 8</h3>
