Answer:
Step-by-step explanation:
You have a fraction, so a non permited value is one which will create a 0 in the denominator.
-3y + 9 = 0
y = 3
Expand the brackets first
5(wx-v) = 9(x + v)
5wx - 5v = 9x + 9v
Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v
factorise out the x
x(9-5w) = 14v
then divide by 9-5w
x = 14v/(9-5w)
Answer:
b=13
Step-by-step explanation:
First, subtract 16 from 94. 94-16=78
Then divide 6 into 78. 78/6=13
Therefore, b=13
