Answer:
Graphic Representation of the Equations is in the image above
Explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = 4x - 5
// Plug this in for variable y in equation [1]
[1] (4x-5) - 2x = -1
[1] 2x = 4
// Solve equation [1] for the variable x
[1] 2x = 4
[1] x = 2
// By now we know this much :
y = 4x-5
x = 2
// Use the x value to solve for y
y = 4(2)-5 = 3
Solution :
{y,x} = {3,2}
