<span>A
student divided the given number by 100 that resulted to 28.003 in his chart.
So what we are looking for this situation is the value of the number before it
was divided by 100.
To get the value, simply multiply the result by 100
=> 28.003 x 100
=> 2800.3
by dividing 100 to the given number, we
simply move the value to the right in a value of hundreds.

Answer: x= (y+z-a)/3
Step-by-step explanation:
You need to move every thing but the x on the other side, so subtract a and divide the whole thing by 3.
You can add, subtract, multiply, and divide things on both sides of the equation as long as you do the same thing to the other side so
if i add n to this side
1-n+n
i must add it to the other side
1-n+n= 7/12 +n
1=7/12 + n
now you must subtract the 7/12 from both sides
1 - 7/12= 7/12 - 7 /12 + n
5/12= n
hope this helps!
