Question. James has 7 more than 4 times the number of Oreos Jordan has. If there are 52 Oreos total, how many does James have?
Answer. 43
What step-by-step reasoning justifies that answer?
Reasoning: Let x be the number of Oreos Jordan has. James has 7 + 4x Oreos. Total: 7 + 4x + x = 52. 5x + 7 = 52. 5x = 45. x = 9. James has 7 + 4(9) = 43 Oreos.
