Answer 1

to check if the expressions are equivalent simplify the expression that is not simplified and see if the results are equivalent

for the first one

`\begin{gathered} 4(5c+3)=9c+7 \\ 20c+12\\e9c+7 \end{gathered}`

the expressions are not equivalent

second expression

`\begin{gathered} 10f-10=2(8f-5) \\ 10f-10\\e16f-10 \end{gathered}`

the expressions are not equivalent

third expression

`\begin{gathered} 12g+21=3(4g+7) \\ 12g+21=12g+21 \end{gathered}`

the expressions are equivalent

forth expression

`\begin{gathered} 6(4j-6)=24-36j \\ 24j-36\\e24-36j \end{gathered}`

expressions are not equivalent
