so the division of a number and -9 or x/-9
+10=11 or
(x/-9)+10=11 subtract 10 from both sides x/-9=1 multiply both sides by -9 x=-9
Your equation would look like this . . .
n/-9 + 10 = 11
*solve by subtracting 10 from both sides, and then multiplying both sides by -9
n = (11 + 10)*-9 = -9
n = -9
The equation from the sentence is − 9 x + 10 = 11 . Solving this yields the number − 9 .
