Answer:
{y,x} = {4,2}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = 2x
// Plug this in for variable y in equation [1]
[1] (2x) - 3x = -2
[1] - x = -2
// Solve equation [1] for the variable x
[1] x = 2
// By now we know this much :
y = 2x
x = 2
// Use the x value to solve for y
y = 2(2) = 4
