Solve the following system of equations 15 x y 2 5x 4y 1
     Solve the following system of equations:  1.5 x - y = -2  -5x + 4y = 14   
  
  Solution
1.5x - y = -2
-5x + 4y = 14
Solving by substitution
From equ 1---> y = 1.5x +2
So, substituting value of y in equation 2:
-5x + 4( 1.5x +2) = 14
-5x +6x +8 = 14
x = 6
y = 1.5x + 2 = 1.5*6 +2 = 11
Solution: x = 6 ; y =11
