a + s = 304
7a + 2s = 1118
Equation 1 is in the correct format.
Equation 2 is in the correct format.
7a + 2s = 1118
7a + 2s - 2s = 1118 - 2s
7a = 1118 - 2s

1(a) + s = 304
1 * ((1118 - 2s)/7) + s = 304
((1118 - 2s)/7) + s = 304
7 * (((1118 - 2s)/7) + s = 304)
7 * (((1118 - 2s)/7) + s = 304)
1118 - 2s + 7s = 2128
-2s + 7s = 2128 - 1118
