Question

5) Solve for x:X - 7.5 = 186) Solve for x:45x = 14.5

Answer 1

We have the following:

5)

$x-7.5=18$

solving for x:

$\begin{gathered} \text{let's add 7.5 on each side} \\ x-7.5+7.5=18+7.5 \\ x=25.5 \end{gathered}$

6)

$\begin{gathered} 45x=14.5 \\ \\ \end{gathered}$

solving for x:

$\begin{gathered} \text{ divide on each side by 45} \\ x=\frac{14.5}{45} \\ x=0.32 \end{gathered}$
