Question

To solve the equation 5+7(x+9)/8 - 12 = 17.5 by undoing the order of operations, what step would you do first?1. Subtract 12 from both sides 2. Divide both sides by 83. Multiply both sides by 8 4. Add 12 to both sides

Answer 1

To solve the next equation:

`5+(7\mleft(x+9\mright))/(8)-12=17.5`

the first step is to add 12 to both sides, as follows:

`\begin{gathered} 5+(7(x+9))/(8)-12+12=17.5+12 \\ 5+(7(x+9))/(8)=29.5 \end{gathered}`
