Equations ů
Linear equations are off the formY=9,X*G X,+ax3
'Mosto
of the time:if
you
have R linear equations in n variables
then you have all of theinto. you heed to solve for all those vaiabla
Example 1;Substitution MethodsI want to know
what
are.
1, Solve one of the equations for one of the variables
how we
い
know
a in terms of b
that variable we solved for into the other equation -
2.Plug
puting rosether like terms and solve for the variable - You should cota
number,
3. Now, plug that variable's valueinto eithe one of theq equati
to find tne other ariable's value.
