nonlinear system acuaciones

A system of equations is nonlinear, where at least one of his equations is not first grade.



The resolution of these systems is usually done by the method of substitution, for it will follow the following steps:

1 unknown is cleared in one of the equations, preferably in the first degree.
y = 7 - x

2 is replaced clear value of the unknown in the other equation.
x ^ 2 + (7 - x) ^ 2 = 25

3rd resulting equation is solved:





4 Each of the values obtained are substituted into the other equation, and obtained corresponding values of the other unknown

x = 3 y = 7 − 3 y = 4
x = 4 y = 7 − 4 y = 3
