How To Solve Y=x?

Replace x with a few numbers and those numbers are what y will equal. For instance-replace x with 1, y now equals 1, replace x with 2, y now equals 2. Replace y with these numbers as well, then you will be able to create a table with sets of ordered pairs to come up with that graph.

Taking value of y=1,2,3,.....
X=1,2,3,...  (since y=x) now plot the points(1,1) (2,2) (3,3) ...  And draw the straight line crossing (0,0)

3x+29=11
7x-y=3

Y + x = -8

Y=x+4

Y=x

This sum is already expressed in its simplest form. From this sum, we can deduce that the varibles x and y are the same number.

It is already solved:
Y=x
and
x=y
