1.Find the value of x in the equation below 3^(2x+1)÷3^(3x-4)×3^(6-7x)=27x

2.Solve the equation 2^(x+y)=8 and 3^(x-y)=1 simultaneously

Step-by-step explanation:

Hello, please consider the following.

Question 1.

Question2.

So, it gives (by adding the two equations) 2x = 3

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
