Best ResponseYou've already chosen the best response.1It tells you the vale of x right ? So just plug in the value of x into equation 2 4y+5y=2 Now solve the equation for y tell me what you get

Best ResponseYou've already chosen the best response.1Good so y=2 Now to solve for x... Now that we know the value of y we can plug in 2 (into equation 1) to figure out the x value 4 x 2 = ?
