We want to solve the following equation
[tex]z\text{ -313=176}[/tex]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
[tex]z=176+313=489[/tex]So the value of z is 489.
