Question

-8j-1=1 how would you solve equations like these

Answer 1

j=-1/4

Explanation:

Given the equation:

`-8j-1=1`

To solve for j, begin by adding 1 to both sides of the equation.

`\begin{gathered} -8j-1+1=1+1 \\ -8j+0=2 \\ -8j=2 \end{gathered}`

Next, divide both sides by the coefficient of j, -8.

`\begin{gathered} (-8j)/(-8)=(2)/(-8) \\ j=-(2)/(8) \end{gathered}`

Finally, reduce the result to its simplest form.

`\begin{gathered} j=-(2)/(2*4)=-\frac{\cancel{2}}{\cancel{2}*4} \\ j=-(1)/(4) \end{gathered}`

The value of j is -1/4.
