Question

Solution of the system x + y = 5 and x - y = 1 is​

Answer 1

Answer:

Solve by Substitution x+y=5 , x-y=1. x + y = 5 x + y = 5 , x − y = 1 x - y = 1. Subtract y y from both sides of the equation. x = 5− y x = 5 - y. x−y = 1 x - y = 1. Replace all occurrences of x x with 5−y 5 - y in each equation. Tap for more steps... Replace all occurrences of x x in x − y = 1 x - y = 1 …
