how to solve?
x+(x-25) =2(x-25) = $365
An equation has only one equal (=) sign. I don't know what the = $365 means. Are you sure you copied the equation correctly?
I'll attempt the solution by ignoring the $365.
$\displaystyle x+(x-25)=2(x-25)$
Firse, since a + precedes the group on the left side of the equation, simply remove the parentheses. Nothing changes.
$\displaystyle x+x-25=2(x-25)$
Distribute (multiply) the 2 across the difference (x-25) on the right side.
$\displaystyle x+x-25=2x-50$
Combine terms on the left side.
$\displaystyle 2x-25=2x-50$
Subtract 2x from both sides.
$\displaystyle 2x-25-2x=2x-50-2x$
$\displaystyle -25=-50$
This is a false statement. Therefore the equation has no solution. I feel like there's an error in the way you presented your problem. Check it and re-post if necessary.
