Question

1/2x-9=-25 what is your answer

Answer 1

first, let's only the expression with x stay on the let side: let's add 9 to both sides of the equation.

$\frac{1}{2} x-9+9=-25+9$
which is
$\frac{1}{2}x=-16$


now, let's multiply everything by 2:

$\frac{2}{2} x=-16*2$
$x=-32$


so the answer is -32!
