Step-by-step explanation:
Solve equation [2] for the variable y
[2] 2y = 11x + 3
[2] y = 11x/2 + 3/2
// Plug this in for variable y in equation [1]
[1] 9x + 2•(11x/2+3/2) = -17
[1] 20x = -20
// Solve equation [1] for the variable x
[1] 20x = - 20
[1] x = - 1
// By now we know this much :
x = -1
y = 11x/2+3/2
// Use the x value to solve for y
y = (11/2)(-1)+3/2 = -4
