A = P + SI

A-P = SI

5425-5000 = 425

THEREFORE THE SIMPLE INTRESTE IS $425

SI = PTR/100

425 = 5000×1×R/100

425×100/5000×1=R

425×100÷5,000×1 = 8.5%

THEREFORE THE RATE IS 8.5%

X + y = 7, for x<br><br><br><br><br><br> ....
Anuta_ua [19.1K]

Answer:

x = -y + 7

    or

x = 7 - y

Step-by-step explanation:

x + y = 7

Step 1: Subtract y from both sides to get x alone.

x + y = 7

   -y    -y

x = 7 - y

Since x is alone and y is a variable & not a number, there's nothing else to do to the equation.
