How can you use the backward problem-solving strategy to solve a two-step equation

Let's use the equation 5x - 20 = 10 as an example for this.

To work backwards from this, you would add the same amount to each side.

You want to isolate the 5x so that you can solve for x.

To do that, you would add 20.

But again, you must add and subtract the same amount to both sides.

So it would look a bit like this:

5x - 20 + 20 = 10 + 20

That would simplify to 5x = 30, or in other words, x = 6.

Basically, you isolate the multiple of the variable then divide the answer to the equation from that multiple.

In the example, 5 is the multiple and after isolating it, the answer was 30.

30 ÷ 5 = 6

x = 6

Hope this helps :)

F - 3/4 = 5/6
Add 3/4 to both sides to get
F = 5/6 + 3/4 = 19/12

Find the surface area of a square prism with a side measure of 6.
Vesnalui [34]
The surface area of any solid is the summation of all the areas of its faces. For a square prism, the surface area is therefore calculated through the equation,
                             A = 6e²
where A is area and e is the measure of the side. 

From the given above, it is stated that the edge of the prism measures 6. Substituting this value to the equation above,
                            A = (6)(6²)
                              A = 216
Therefore, the surface area of the given prism is equal to 216 square units.
