X=-3 because 5x-3=-15, -15-7 =-22
a) T = 4K / M
1) multiply both sides by M => TM = 4K
2) divide both sides by 4 => K = TM / 4
Answer: K = TM / 4
b) bm - Kn = 14
1) add Kn to both sides => bm = 14 + Kn
2) subtract 14 from both sides => bm - 14 = Kn
3) divide both terms by n => K = [bm - 14] / n
Answer: K = [bm - 14] / n
