Okay so i would do this with a logarithm.
5^(2x) = 28
take the log of both sides
log5^(2x) = log28 and because of this log rule: logA^n = nlogA
(2x)log5= log28
then divide by log5 on both sides
2x = log28 / log5
and divide by 2
x = (log28 / log5) /2
this can be found with a calculator:
x= about 1.03521...
round that to whatever the question says to
If you can graph in slope intercept, your new equations would be: y= -2x-1 and y= 2/3x-3.
Just graph those now since it should be easier.

Step-by-step explanation:
85.82 is closet to 85.80 snice 2 is a low number
Answer:
Final result :
5y2
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "y2" was replaced by "y^2". 1 more similar replacement(s).
Step by step solution :
Step 1 :
Trying to factor as a Difference of Squares :
1.1 Factoring: x-y2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : x1 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares
Equation at the end of step 1 :
(2x + (3 • (y2))) - 2 • (x - y2)
Step 2 :
Equation at the end of step 2 :
(2x + 3y2) - 2 • (x - y2)
Step 3 :
Final result :
5y2
