how do you know when the solution of equations is a precise answer and when it is an approximate answer?
an answer is precise when it is an exact number like 10, 2, or 123.
An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11
Well once you get a value for x and y and you plug it back to the equation both of the equation should be equal if the answer is wrong they will not be equal
