3/4x-1/2y=12 ax-by=9
what is the value of a/b

Step-by-step explanation:

Hello,

I assume that we are looking for a and b so that

ax - by = 9

<=>

we can notice that 12 = 4 * 3

so we need to multiply by 3 and divide by 4 to get 9 from 12

Then, we can identify a and b

Then

hope this helps

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
