Question

Is 5 a solution to the equation x + 3 = 8

Answer 1

`\boxed{x=5}`

Solution Steps:

______________________________

1.) Subtract 3 from both sides:

• 
  `3-3=` Cancels Out

• 
  `8-3=5`

- When solving problems like these (One-Step Equations,) to get x alone you must do the opposite of what you see.

- In this situation we have a positive 3. So to get rid of both numbers you do the opposite: Opposite of +3 is -3. So you subtract 3 from each number.

Answer 2

yes because when you replace x with 5 you get the equation 5+3=8 and 5+3 is in fact 8 so 8=8
