Question

x+y=1,2x-y=5 solve these simultaneous equations​

Answer 1

Answer:

x=2,y=-1

Step-by-step explanation:

x+y=1 (1)

2x-y=5 (2)

adding equation 1 and 2

x+y=1

2x-y=5

3x+0=6

x=2

place x=2 in equation 1

so

2+y=1

y=1-2

y=-1

therefore solution is (x,y)=(2,-1)

Answer 2

Answer

X=2,Y= -1

step –by –step explanation :

X+Y=1 (1)

adding equation 1and2

x+y=1

2x-y=5

3x+0=6

x=2

place x=2 in equation 1

so

2+y=1

y=1-2

y=-1

therefore solution is (x, y) = (2,-1)
