Question

Solve the equation: f+8=13

Answer 1

`f\text{ = 5}`

Step-by-step explanation:

Here, we want to solve the given equation

To do this,we have to isolate f on the left hand side of the equation

To do the isolation, we have to bring 8 to the right

What this mean is that it is going to cross the equality sign and that changes its sign from positive to negative

Mathematically, we have this as:

`\begin{gathered} f\text{ + 8 = 13} \\ f\text{ = 13-8} \\ f\text{ = 5} \end{gathered}`
