c + s = 300
3c + 1.5s = 825
Equation 1 is in the correct format.
Equation 2 is in the correct format.
3c + 1.5s = 825
3c + 1.5s - 1.5s = 825 - 1.5s
3c = 825 - 1.5s

1(c) + s = 300
1 * ((825 - 1.5s)/3) + s = 300
((825 - 1.5s)/3) + s = 300
3 * (((825 - 1.5s)/3) + s = 300)
3 * (((825 - 1.5s)/3) + s = 300)
825 - 1.5s + 3s = 900
-1.5s + 3s = 900 - 825
