$x^2-3x=-8\\\\x^2-3x+2.25=-5.75\\\\(x-1.5)^2=-5.75\\x-1.5=\pm i\sqrt{5.75}\\\boxed{x=1.5 \pm i\sqrt{5.75}}$

Not the prettiest but you can simplify

Answer:

$x=2$

Step-by-step explanation:

$9(x+1) = 25+x$

Distribute the 9:

$9x+9=25+x$

Subtract x on both sides:

$8x+9=25$

Subtract 9 on both sides:

$8x=16$

Divide both sides by 8:

$x=2$
