Answer:
and 
the mistake was in calculating 
let's solve first.
Step-by-step explanation:
if 
, substitute the 
in the equation
as
solve the equation in parentheses :
multiply 
by 
it will equal to: 
now we want to let all unknown digits alone, so we will take 
to the other side with a different sign it will be as:
now we will solve it:
at this part, the given equation was wrong in the paper.
we don't want the digit to be negative so we will do it like this:
now that we found 
we will substitute it to find 
:
overall the mistake was in calculating instead of putting
he/she put a different sign in front of the digit like :
so when he/she flipped 
it became positive and instead of subtracting he/she added it.
Answer:
Step-by-step explanation:
sir in the graph every point is (X,Y) so you should choose consecutive random numbers for the X values for the first point after that put the values you choose In the equations so now you have just numbers in the equation .. add, subtract and multiply at the end you will get a value .. ok this Y for the first point .. mark this point on the graph and continued this process until it reached at least 3 points, and connected between them.
Note : do this with each equation separately and do not connecte between two points for two different equations
the equation with x will become as line
the equation with x² will become as arch
after you finsh drwaing see the points that the tow equation are touching within and write them. Usually it is two points
