Question

Find the solution.7 · x = 8412139177

Answer 1

We need to find the value for x using the inverse operation:

Then:

`\begin{gathered} 7-x=84 \\ \end{gathered}`

Let us solve for x:

The x is subtracting, so it will add up to the other side:

`7=84+x`

Now, the 84 is positive, so it will be negative on the other side:

`\begin{gathered} 7-84=x \\ x=-77 \end{gathered}`

Hence, the solution for x is -77.
