What is the solution to -8x=72 and why?

Answer 1

So we need to find the value of x.

_{-8x =72}

Let's divide it by 8 on both sides.

_{-8x/8 = 72/8}

so we have,

_{-x = 9}

Since we want the value of x and we have a negative x value. Let's multiply by -1 on both sides which gives,

_{(-1)(-x) = (-1)(9)}

which is

_{x = -9. as negative times negative makes positive on right hand side.}

So the value of x is -9.
