Answer :
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
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
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
x/-9
+10=11 or
(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9
