Step 1: -9+n=-18. You would add the inverse to both sides, meaning you’d add nine to the negative nine to cancel it out and then then 9 to -18.
-9+n=-18
+9 +9
That would leave you with the equation: n=-9, since -18 plus a positive 9 equals a negative nine. You’re final answer is n= -9.
You can check you answer by substituting the variable with the solution (-9).
-9 + -9= -18

Answer:
I got -y^2 - 9y -4 (I hope it helps)
Step-by-step explanation:
4y^2 - 5y^2= -y^2
7-11= -4
-6y + -3y= -9y
-y^2 -9y -4

hope this helps ^^
Step-by-step explanation:
you multiply both sides by the same factor, so that the main message or information, the ratio, stays the same :
3:6 × 2/2 = 6:12
3:6 × 1/3 / 1/3 = 1:2
3:6 × 4/3 / 4/3 = 4:8
3:6 × 100/100 = 300:600
so, these are all equivalent ratios. and there are infinitely more, as you can see.
