Answer:
True for all value of the variables involved .
Explanation:
While solving system of equations if we have the left and right sides equal then we say the system of equaitons have infinite number of solutins.The equation is true for all values of x .
For example we have x+4=x+4 .
Subtracting x both sides we have 4=4.
That is the equation is true for all values of x .x can take any values.It is set of real numbers.
