Final answer:The expression 5x - 3y represents a linearequationin two variables, x and y.Explanation:The given expression, 5x - 3y, represents alinearequation in two variables, x and y.In this equation, the coefficient of x is 5 and the coefficient of y is -3. This means that for every 1 unit increase in x, there will be a 5 unit increase in the value of the expression, and for every 1 unit increase in y, there will be a 3 unit decrease in the value of the expression.For example, if x = 2 and y = 4, then 5x - 3y = 5(2) - 3(4) = 10 - 12 = -2.Learn more about Linear Equations here:brainly.com/question/32634451#SPJ1...
