Answer:
what are the options
Step-by-step explanation:
????????????????????????????????
Simplify. Combine like terms
7y - 3y = 4y
-12 + 9 = -3
----------------------------------------------------------------------------------------------------------------
4y - 3 = 0
Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.
4y - 3 (+3) = 0 (+3)
4y = 3
4y/4 = 3/4
y = 3/4
-----------------------------------------------------------------------------------------------------------------
y = 3/4 is your answer

U = vw + z
vw + z = u |subtract z from both sides
vw = u - z |divide both sides by w
v = (u - z)/w
