Make x the subject! urgent help
Serhud [2]

Answer:

x =  \frac{n}{b -  {t}^{2} }

Step-by-step explanation:

I supposed that is a "n".

Steps as below:

{t}^{2}  = b -  \frac{n}{x}  \\ b -  \frac{n}{x}  =  {t}^{2}  \\  -  \frac{n}{x}  =  {t}^{2}  - b \\  \frac{n}{x}  =  - ( {t}^{2}  - b) \\  \frac{n}{x}  = b -  {t}^{2}  \\ n = x(b -  {t}^{2} ) \\ x(b -  {t}^{2} ) = n \\ x =  \frac{n}{b -  {t}^{2} }

Find solution to the system of linear equations. 5x1 + x2 = 0 , 25x1 + 5x2 = 0
Zigmanuir [339]

Answer:

the system of equation has infinite solution

Step-by-step explanation:

5x_1 + x_2 = 0 , 25x_1 + 5x_2 = 0

Solve the first equation for x_2

Subtract 5x1 on both sides

5x_1 + x_2 = 0

x_2 =-5x_1

Now substitute -5x1 on second equation

25x_1 + 5x_2 = 0

25x_1 + 5(-5x_1)= 0

25x_1-25x_1= 0

0=0

So the system of equation has infinite solution
