5c + 3t = 37
2c + 6t = 64
Equation 1 is in the correct format.
Equation 2 is in the correct format.
2c + 6t = 64
2c + 6t - 6t = 64 - 6t
2c = 64 - 6t

5(c) + 3t = 37
5 * ((64 - 6t)/2) + 3t = 37
((320 - 30t)/2) + 3t = 37
2 * (((320 - 30t)/2) + 3t = 37)
2 * (((320 - 30t)/2) + 3t = 37)
320 - 30t + 6t = 74
