I hope this is what you're looking for. The concept of regrouping<span> (borrowing) is so that students can see what actually happens in it. For example, to </span>subtract <span>52 − 38, we write 52 as 50 + 2 (breaking it down into its tens and ones). Then, </span>regrouping<span> means that 50 + 2 becomes 40 + 12.</span>

Step-by-step explanation:
It was just in my notes....
Ivan will need 24 cans. 56/10 = 5.6. Each can is 5.6 cm tall. 162.4-28 =134.4
134.4/5.6 = 24
2/5x + 1.5y = 7x - 2y
1.5 y + 2y = 7 x - 2/5x
You can this
1.5 y + 2y = 7x - 0.4x
3.5y = 6.6x
