Question

In the given system x-y=-1 and 2x+y=4, the solution is _ because the values satisfy the given equations

Answer 1

Answer:

x = 1

y = 2

Step-by-step explanation:

x - y = -1

x = y - 1

Putting in second equation:

2( y - 1) + y = 4

2y - 2 + y = 4

3y = 6

y = 2

x = y - 1

x = 2 - 1

x = 1
