Question

match the 3 equations with an equivalent equation. some of the answers are not used3x+6=4x+73(x+6)=4x+74x+3x=7-6__________________________________Answer choices: 7x=13x-1=4x9x=4x+73x=4x+73x+18=4x+7

Answer 1

We have the following:

`\begin{gathered} 3x+6=4x+7 \\ 3x=4x+7-6 \\ 3x=4x+1 \\ 3x-1=4x \end{gathered}`

Therefore:

3x+6=4x+7 //// = //// 3x-1=4x

`\begin{gathered} 3\mleft(x+6\mright)=4x+7 \\ 3x+18=4x+7 \end{gathered}`

3(x+6)=4x+7 //// = //// 3x+18=4x+7

`\begin{gathered} 4x+3x=7-6 \\ 7x=1 \end{gathered}`

4x+3x=7-6 //// = //// 7x=1
