 Drag the steps shown at the right, one by one in the correct order, so they line up under the question to form a solution. Ignore the purple letters while you are choosing the steps.
Now read the purple letters downward, and move your cursor over the box at the right to see if the letters match. If they do, you placed the steps in the correct order.
To check this equation, you can't use the decimal, as it is infinite in length. Rounding it will mean that the check won't work. You'll need to check the fractional answer. Here's that work: 
As in all checks, we didn't use algebraic solving, in case there was an error that we might repeat. We just substituted the answer and worked out both sides. It goes without saying that you need to be good at working with fractions. Go back and try the examples again if you need to, or return to the main Equations menu and practice a new type of equation. |
