<em>To solve for a variable, you just need to isolate the variable to one side.</em>
<h3>7.</h3>For this, just divide both sides by r and <u>your answer will be </u>
For this, divide both sides by nR and <u>your answer will be </u>
Firstly, multiply both sides by T:
Next, subtract FV on both sides of the equation:
Lastly, multiply both sides by -1, and <u>your answer will be </u>
Firstly, multiply both sides by 1000:
Lastly, divide both sides by tc and <u>your answer will be </u>
Using the information from the question, one can construct two equations:
... (1)
... (2)
by substituting (1) into (2) to find x
\frac{5}{4z} = \frac{1}{4}
⇒ z = 5
By substituting value of z into (1)
⇒ 4 (5) = x
⇒ x = 20
Thus the two numbers are 5 & 20
by substituting (1) into (2) to find x
\frac{5}{4z} = \frac{1}{4}
⇒ z = 5
By substituting value of z into (1)
⇒ 4 (5) = x
⇒ x = 20
Thus the two numbers are 5 & 20
