An equivalent equation has been written by multiplying the second equation by 2. 4x – 9y = 7 → 4x – 9y = 7 2(–2x + 3y = 4) → –4x
+ 6y = 8 What is the solution to the system? ((negative StartFraction 19 over 2 EndFraction, negative 5), –5) (–5, (negative 5, negative StartFraction 19 over 2 EndFraction)) ((negative StartFraction 15 over 2 EndFraction, negative StartFraction 11 over 3 EndFraction), ) ((negative StartFraction 19 over 10 EndFraction, StartFraction 1 over 15 EndFraction), )
Different thinking levels created sectionalism as people began to realize more about the world and people were educated enough to form their own ideas and have critical thinking skills.
