Question

Drag the tiles to the boxes to form correct pairs.Match the palrs of equivalent expressions.(-14 +30)–(1+36)46+13(5+26)+(26+)86-15(56–3)–(8+66)16–11(-10+6)+(76–5)– 15 - 26

Answer 1

Kindly check below.

1) Examining the expressions inside the tiles, we can tell that:

`\begin{gathered} (-14+(3)/(2)b)-(1+(8)/(2)b)=-(5)/(2)b-15 \\ 4b+(13)/(2) \\ (5+2b)+(2b+(3)/(2))=4b+(13)/(2) \\ 8b-15 \\ ((7)/(2)b-3)-(8+6b)=(7)/(2)b-3-8-6b\rightarrow-11-(5)/(2)b \\ -(5)/(2)b-11 \\ (-10+b)+(7b-5)=8b-15 \\ -15-(5)/(2)b \end{gathered}`

2) Based on this we can tell the following relationship of equivalence:
