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:

$5+\frac{7\mleft(x+9\mright)}{8}-12=17.5$

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

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