Alright — let's do this. a) 2 × + 13 = 37 Step 1: Isolate the term with . 2 × = 37 - 13 2 × = 24 Step 2: Solve for . = (24)/(2) = 12 Using the train and improvement method: | problem solution () | test | conclusion | |---|---|---| | 10 | 2 × 10 + 13 = 20 + 13 = 33 | 33 < 37, too low | | 15 | 2 × 15 + 13 = 30 + 13 = 43 | 43 > 37, too high | | 12 | 2 × 12 + 13 = 24 + 13 = 37 | 37 = 37, correct | The solution is = 12. b) 14 × - 21 = 77 Step 1: Isolate the term with . 14 × = 77 + 21 14 × = 98 Step 2: Solve for . = (98)/(14) = 7 Using the train and improvement method: | problem solution () | test | conclusion | |---|---|---| | 5 | 14 × 5 - 21 = 70 - 21 = 49 | 49 < 77, too low | | 10 | 14 × 10 - 21 = 140 - 21 = 119 | 119 > 77, too high | | 7 | 14 × 7 - 21 = 98 - 21 = 77 | 77 = 77, correct | The solution is = 7.
