Question

How do you solve letter b using a subtraction equation with one variable that has a solution of 2/3

Answer 1

Let x be the variable. Then, a subtraction equation which involves the variable x and 2/3 as a result could be:

`x-(1)/(3)=(1)/(3)`

because, x wil be given as

`\begin{gathered} x=(1)/(3)+(1)/(3) \\ x=(2)/(3) \end{gathered}`
