Question

Solve the equation z-313=176. Use a graphic method to illustrate the equation

Answer 1

We want to solve the following equation

`z\text{ -313=176}`

So, we can have the following representation of the equation using blocks

So, if we take z and remove 313, we would get 176.

Now, to solve the equation we add 313 on both sides, so we get

`z=176+313=489`

So the value of z is 489.
