We have all of the variables on the left. Now, keep going. What move can you make next to get rid of 60 on the left so that the x term, 10x, is alone on the left?

Olivia's miles
=
Addison's miles

60+20x
=
90+10x

10x

10x

60+10x
=
90

Add 60 to both sides

Add 10x on both sides.

Subtract 60 from both sides

1 answer

To isolate the \(10x\) term and get rid of the \(60\) on the left side, you should subtract 60 from both sides of the equation.

Here's how the next step would look:

Starting with: \[ 60 + 10x = 90 \]

You subtract \(60\): \[ 60 + 10x - 60 = 90 - 60 \] This simplifies to: \[ 10x = 30 \]

Now, the \(60\) is gone, and the equation is simplified so that the \(x\) term is isolated on the left.
