Answer:
Step-by-step explanation:
You need to find “Y.”
To find “Y”, you do
-3 - 4y = 12
+3 +3
which would be -4y = 15
divide both sides by -4, and you get
y = 15/-4
Then you plug 15/-4 into “Y”, so you get -3 - 4(15/-4) = 12
then multiply, and you get -3 + 15 = 12
Answer:
-3.75
Step-by-step explanation:
You will add positive 3 to both side so -3+3=0 which cancels that out and then You add 3+12=15 and you get -4y=15so you divide both by -4 and you get y=-3.75
