-x+3y=4

2x - 4 = 2y

Consider the given system of equations. If (x, y) is the solution to the

system, then what is the value of x-y?

Final answer:To find the value of x-y, solve the system of equations to find the values of x and y. Then subtract y from x to find the value of x-y, which is 2.Explanation:To find the value of x-y, we first need to solve the given system of equations:Equation 1: -x+3y=4Equation 2: 2x - 4 = 2yLet's solve the second equation for y:2x - 4 = 2yy = (2x - 4)/2y = x - 2Now substitute this expression for y in the first equation:-x + 3(x - 2) = 4-x + 3x - 6 = 42x - 6 = 42x = 10x = 5Substitute the value of x in the second equation to find y:y = 5 - 2y = 3Therefore, x-y = 5 - 3 = 2.Learn more about solving systems of equations here:brainly.com/question/29050831...
