Section 7.2: Exercises 52, 72, 78Solve each system by substitution. Determine whether theequations are independent, dependent, or inconsistent.52). X – Y = 100.1x + 0.5y = 1372). X + 6y = -25x – 20y = 578). Y – 2x = -7.53x – 5y = 3.2Need help asap? Can someone assist me with these three problems?

52.x − y = 10 and 0.1x + 0.5y = 13 second equation same as x + 5y = 130 sowe havex − y = 10 (1) x + 5y = 130 (2) from (1) we have x = 10+y Putting this in equation (2) we have 10+y +5y =...
