Given that the student wrote a $700 check, and had a balance of $650 in his account after writing the check.

To find how much he had before writing out the check, we would create a linear equation to do this.

Let x = His balance before writing the check.

Therefore, we would have the linear equation below, which is gotten when we subtract the check from how much he had before.

[tex]\begin{gathered} \therefore Linear\text{ equation} \\ x-700=650 \\ \end{gathered}[/tex]

ANSWER 1: x-700 =650

The next step is to solve for his starting balance.

[tex]\begin{gathered} x-700=650 \\ x=650+700 \\ x=1350 \end{gathered}[/tex]
