Transcript
Question 13 Write 4 equations whose solution is u = 6.To do this, we start with u = 6 and do the same thing to both sides. Here are 5 examples: Multiply by 2 2 × u = 2 × 6 2u = 12 Add 10 u + 10 = 6 + 10 u + 10 = 16 Multiply by 5 , then add 3 5 × u + 3 = 5 × 6 + 3 5u + 3 = 30 + 3 5u + 3 = 33 Subtract 5 u – 5 = 6 – 5 u – 5 = 1
