Question

Solve each equation for the variable. a/3 - 1.2 = 0.4

Answer 1

We have the following equation

`(a)/(3)-1.2=0.4`

If we move -1.2 to the right hand side as +1.2, we get

`\begin{gathered} (a)/(3)=0.4+1.2 \\ (a)/(3)=1.6 \end{gathered}`

Now, we must move 3 to the right hand side as

`a=3(1.6)`

and finally, the answer is

`a=4.8`
