Question

-what is 1/4x-9=-15?

Answer 1

First you had to add by nine from both sides of equation form.

$\frac{1}{4}x-9+9=-15+9$

Then simplify by equation.

$\frac{1}{4}x=-6$

Next multiply by four from both sides of equation form.

$4*\frac{1}{4}x=4(-6)$

Finally simplify by equation.

$x=-24$

Final answer: $\boxed{x=-24}$

$6*4=24$

$4*6=24$

$24/6=4$

$24/4=6$

Hope this helps!
