Question

Solve for X and y 
4x +y/3 =8/3
X/2 + 3y/4 = -5/2
​​​​​​


Solution

4x + y/3 = 8/3       (1)
x/2 + 3y/4 = -5/2    (2)

(2) x 8 => 
                  4x + 6y = -20       (3)

(3) - (1)  => 
                    6y - y/3 = -20 - 8/3
                    17y/3 = -68/3
                     17y = -68
                      y = -68/17
                         y = -4      (4)

substitute (4) in (3)   
                             => 4x + 6 X -4 = -20
                                  4x + -24 = -20
                                  4x = -20 + 24
                                  4x = 4
                                   x = 1

=>   x = 1 , y = -4
