3= -1 + 7y x 10 to the second power
Let's solve your equation step-by-step.
39−2(x−8)=56
Step 1: Simplify both sides of the equation.
39−2(x−8)=56
39+(−2)(x)+(−2)(−8)=56(Distribute)
39+−2x+16=56
(−2x)+(39+16)=56(Combine Like Terms)
−2x+55=56
−2x+55=56
Step 2: Subtract 55 from both sides.
−2x+55−55=56−55
−2x=1
Step 3: Divide both sides by -2.

Answer:
1,047
Step-by-step explanation:
n = distance from Boston to St. Louis
2410 is 230% of n
2410 = 2.3n
2410/2.3 = n
1,047 miles = n
This is pretty simple once you figure out the trick.
All you have to do is make the args common.
Meaning
is nothing but 
Which is nothing but:
.
Now using the scorpion tail method, this equation can be reframed to being:
. You bring 6 to the other side and it'll become: 
Factorise it and you get: 
Henceforth, the solution would be
and
