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:
y = -4
Step-by-step explanation:
-4y - 3 + 3y = 8 - 2y - 15
~Combine like terms
-y - 3 = -2y - 7
~Add 3 to both sides
-y = -2y - 4
~Add 2y to both sides
y = -4
Best of Luck!
Answer:
A
Step-by-step explanation:
Expand parentheses:
Move all y's to one side and numbers to the other:
Divide both sides by -6. Since you are dividing both sides by a negative number, you need to flip the comparator:
Hope this helps!
can u pls provide the diagram
Answer:
