Solving:
-7 + y = 3 + 2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-7 + y + -2y = 3 + 2y + -2y
Combine like terms: y + -2y = -1y
-7 + -1y = 3 + 2y + -2y
Combine like terms: 2y + -2y = 0
-7 + -1y = 3 + 0
-7 + -1y = 3
Add '7' to each side of the equation.
-7 + 7 + -1y = 3 + 7
Combine like terms: -7 + 7 = 0
0 + -1y = 3 + 7
-1y = 3 + 7
Combine like terms: 3 + 7 = 10
-1y = 10
Divide each side by '-1'.
y = -10
Hope it helps. (:

<span>Normally when they tell you interest rate they say per annum meaning the percent interest rate for a year.
But in this problem they seem to say John pays 12% for a 146 day loan.
So interest = P * r / 100 = 8400 * 12/100 = $1,008.00
Maturity value = Principal + Interest = 8400 + 1008 = $9,408.00</span>

Step-by-step explanation:
Answer:
(x-43.45)(x+7.45)=0.
Step-by-step explanation:
We have the quadratic equation 
i.e. 
Now, the roots of the quadratic equation 
are given by 
So, from the given equation, we have,
a = 1, b =-36 , c = -324.
Substituting the values in , we get,
i.e. 
i.e. 
i.e. 
i.e. 
and i.e. 
i.e. 
and i.e. 
i.e. x = 43.45 and x = -7.45
Hence, the factored form of the given expression will be (x-43.45)(x+7.45)=0.
