Question

Answer 2

what do u mean

Answer 3

\[-87+9x=x+81\]
to solve for x, we want the numbers with an x on one side of the equality and the constants on the other, let's do that:
\[9x-x=81+87\]
operating, we get:
\[8x=168\]
So let's isolate that x:
\[x=\frac{ 168 }{ 8 }\]
\[x=84\]
And that's done :)
