Hello,
{x=y-3
{x+3y=13;
{x=y-3
{y-3+3y=13;
{x=y-3
{4y=13+3;
{x=y-3
{4y=16;
{x=y-3
{y=16:4=4;
{x=4-3=1
{y=4;
{x=1
{y=4
the solution to the system of equations is (1,4)

Answer:
Any real number
Step-by-step explanation:
Let your no.= x
double the number=2x
add 4 = 2x+4
subtract same number=2x+4-x
subtract 3=2x+4-x-3
get number plus 1=x+1
so equation we get
2x+4-x-3=x+1
x+1=x+1
x=x
it means x is equal to all real number
So your number can be any real number
