Question

Solve the equation. You may find using algebra tiles to be helpful. 2x + 9 = 15

Answer 1

• 
  `\boxed{\bf{x=3}}`

Explanation:

Hello! The first step in solving our equation is subtracting 9 from both sides. Upon doing this, we obtain:
`\bf 2x=15-9`, which later simplifies to
`\bf 2x=6`.

Then, we need to divide both sides by 2, since both sides are multiplied by 2. Remember, we always use inverse operations to solve equations.

We arrive at
`\boxed{\bf{x=3}}`, which is our final answer.

I hope it helped! :)
