Answer:
2.3p – 10.1 = 6.49p – 4
230p – 1010 = 650p – 400 – p
Step-by-step explanation:
……………………………………………
2.3p – 10.1 = 6.5p – 4 – 0.01p
⇔ 2.3p – 10.1 = (6.5p – 0.01p) – 4
⇔ 2.3p – 10.1 = (6.5 – 0.01)p – 4
⇔ 2.3p – 10.1 = (6.49)p – 4
⇔ 2.3p – 10.1 = 6.49p – 4
_______________________
⇔ 100 × (2.3p – 10.1) = 100 × (6.5p – 4 – 0.01p) <u><em>multiply both sides by 100</em></u>
⇔ 100 × (2.3p – 10.1) = 100 × (6.5p – 4 – 0.01p)
⇔ 230p – 1010 = 650p – 400 – p
