Solve for the variable. x ÷ -9 = -7 A. -16 B. -2 C. 0.8 D. 63

frutty [35]

If your equation is $\frac{x}{-9} = -7$ , the only thing you need to do to get x by itself is to get rid of the denominator, the $-9$ . To get rid of a denominator, you multiply both sides by it, so you're left with

$x=-9*-7$ so $x=63$
