3m + 4c +7d = 5.45 => m = (5.45 - 4c - 7d)/3;
One solution is c = -1, d = 0, m =3.15; and so on .........
i dont know but good luck ;
To solve for m , c , and d in the equation 3 m + 4 c + 7 d = 5.45 , we can express one variable in terms of the others since we have more variables than equations. The expressions become m = 3 5.45 − 4 c − 7 d , c = 4 5.45 − 3 m − 7 d , and d = 7 5.45 − 3 m − 4 c . This allows for multiple solutions based on chosen values for two of the three variables.
