I’m guessing it’s the first one
Answer:
x = 1/7
Step-by-step explanation:

x = 1/7
You multiply by 10 or more
R is the root of 12 so you would divide r and 12 but are is the 18 number in the alphabet so it’s 18 divided by 12 and the answer is 1.5
Answer:
(24, -15)
Step-by-step explanation:
-3x + 4y = 12
3x – 6y = 18
Add the two equations together to first solve for y
-2y=30
y=-15
Enter -15 into one of the equations to solve for x
-3x + 4(-15) = 12
-3x-60=12
-3x=72
x=24
