Cost of Squash = s      cost of 5 squash =   5s

     5s + 2z = 132

     3s+   z  = 75     Multiply through by -2 to make this equation equal to:

     -6s -2z=-150    now add top and bottom equations

 

-s = -18        s = 18 cents

 

Substitute in this value of s into one of the equations to find z

 

3s + z = 75

3(18) + z = 75

z = 21 cents
