Five equations and five unknown variables. Substitution will work.

The variable M is used three and the most occurances. Try substituting for this, first in all the other equations. Pick any equation containing M to start this.

M+G=33
M=33-G
-
Now substitute to make the changes.

Simplify this system.


------Four equations in four unknown variables. Look to see that two of them use only S and G, and those two by themselves as a system make using the Elimination Method very convenient for first solving the values of S and G.

You should find from that and .

You may then see a path to handle the other equations shown in this four-with-four system.
