You can multiply either the top or bottom equation by -1 so lets say you apply it to the bottom equation it’ll look like this:
-9x + 9y = 18
6x - 9y = 12
then the +9y and -9y will cancel out
-9x = 18
6x =12
then you add the two equations together
-3x = 30
divide both sides by -3
x = -10
Answer:
13 is your answer
Step-by-step explanation:
x - 8.1 = 5.3
+8.1 +8.1 Add 8.1 to both sides
x = 13.4
Which if you want the whole number i'd be 13, Because if your rounding the 3, 4 won't bump the 3 up any because 4 isn't greater than 5.
Hope my answer has helped you!
