Question

Solve the equation Mentally

Answer 1

Given:-

`\begin{gathered} 8+j=15 \\ \end{gathered}`

To Find:-

The value of j.

To find the value of j, we need to keep j at one side of the equal to sign and take all other number to the other side of the equal to sign.

`\begin{gathered} 8+j=15 \\ j=15-8 \\ j=7 \end{gathered}`

So now the value of j has been found. The value of j is 7.
