Use this equation: P*r*t. Plug in the percentage, rate, and time (years) to solve for your interest! It's a simple problem and It would be good if you used that equation for these problems. Hope it helps!

6x + 7y = 1<br> 8x – 3y = 25<br> Solve me fast explainly
Elenna [48]

Answer:

{x,y} = {89/37,-71/37}

Step-by-step explanation:

 8x = 3y + 25

 [2]    x = 3y/8 + 25/8

Plug this in for variable  x  in equation [1]

  [1]    6•(3y/8+25/8) + 7y = 1

  [1]    37y/4 = -71/4

  [1]    37y = -71

Solve equation [1] for the variable  y  

  [1]    37y = - 71

  [1]    y = - 71/37

By now we know this much :

   x = 3y/8+25/8

   y = -71/37

Use the  y  value to solve for  x  

   x = (3/8)(-71/37)+25/8 = 89/37
