Answer:2x-5y=17;6x-5y=-9
Step-by-step explanation:
Solve equation [2] for the variable x
[2] 6x = 5y - 9
[2] x = 5y/6 - 3/2
// Plug this in for variable x in equation [1]
[1] 2•(5y/6-3/2) - 5y = 17
[1] - 10y/3 = 20
[1] - 10y = 60
// Solve equation [1] for the variable y
[1] 10y = - 60
[1] y = - 6
// By now we know this much :
x = 5y/6-3/2
y = -6
// Use the y value to solve for x
x = (5/6)(-6)-3/2 = -13/2
