Answer:
x = 7
Step-by-step explanation:
You solve a linear equation by putting the variable on one side of the equal sign and a constant on the other side. Here, variables and constants are on both sides of the equal sign, so you need to separate them.
The basic idea is that you add the opposite of any term you don't want. Whenever you perform any operation (like "add"), <em>you must do it to both sides of the equation</em>.
We observe that x-terms have coefficients of 10 and 9. We choose to add the opposite of 9x to both sides:
10 -9x -5 = 9x -9x +2
x -5 = 2 . . . . simplify
Now, we still have -5 on the left, where we don't want it. So, we add its opposite (+5) to both sides:
x -5 +5 = 2 +5
x = 7 . . . . simplify
The solution is x = 7.

<em>Additional comment</em>
If we were to end up with an x-coefficient other than 1, we would divide both sides of the equation by that coefficient. This will leave the x-term with a coefficient of 1.
Answer:
$72,100
Step-by-step explanation:
To calculate the total principal+interest payment, you can use the formula to find the future value:
FV=PV(1+i)^n
FV= Future value
PV= Present value= $58,200
i= Interest rate= 7.40%
n= Number of periods of time= 3 years
Now, you can replace the values on the formula:
FV=58,200*(1+0.0740)^3
FV=58,200*(1.0740)^3
FV=72,100
According to this, the answer is that the total principal + interest payment will be $72,100.
$12/25 pounds
12/25= $0.48
$0.48/pound is your answer
