Now that you have all the s terms on the left, you can start thinking about how to make sure the constant numbers are only on one side of the equation. What move can you make to get rid of the −10 on the left, so that all the constant numbers are on the right, while keeping the equation balanced?

Question

2s − 10
=
−3s − 8
+
3s
+
3s

5s − 10
=
−8

Multiply both sides by 10

Subtract 10 from both sides

Divide both sides by 10

Add 10 to both sides

Answer 1

To ensure that all the constant numbers are on one side of the equation, you can add 10 to both sides.

Applying this to your equation:

From: \[ 5s - 10 = -8 \]

If you add 10 to both sides, you get: \[ 5s - 10 + 10 = -8 + 10 \] \[ 5s = 2 \]

So the correct move is to add 10 to both sides.
