9x-84=4x-18
5x=66
x=13.2
your number is 13.2
Ln(6)=ln(3^2)=2*ln(3)
so 2*ln(6) = 4*ln(3)
so 2*ln(6) - ln(3) = 3*ln(3)
You cant solve y but you can form an equation in terms of y
which is y=7-2x
if you were given another equation that has the term y and x than you can solve it.also that is a simultaneous equation.
Hope this helps,dont forget to put this as the brainliest answer if it does to help me out too. xD
Answer:
r=(a/b)-1
Step-by-step explanation:
