what is equation? definition, facts and example, by MATHQUESTION.IN SOLVE IT a⁴ + b⁴ + c⁴=?

what is equation  an equation can be defined as a mathematical statement that has equal a symbol between two values 2a+3b=13.   in the side is 2a+3b is equal to 13 what is equation  and EXAMPLE  like    1+2+3=6,             OR       2A+3B=13          A+B+C=D                          3A+4B=18   SOLVE EXAMPLE give you one question and  solve it let i solve a example equation it 2a+3b=13 AND  3a+4b=18. .....eq 2 solve:    2a+3b=13               a= (13-3b)/2  ..eq 1 then put in eq 1 to eq 2               3[ (13-3b)/2 ] +4b =18                39-9b+8b=36                  -b = 36-39                    -b= -3                       b=3     eq      3  and fine vlue of a                       put eq  3 in  eq   1                    a= (13-9)/2                        =4/2=2  let  vlue of a and b is 2, 3 ONE MORE Q.. a + b + c=4 a²  + b²  + c² .=10  a⁴ + b⁴ + c⁴=?  All right so,simultaneous equations... two main methods to deal with these: one is substitution and the other one is elimination. Now I did actually try this …
