Question

solve the following pair of linear equation by substituting method 2x-y=2,x-y=3​

Answer 1

Answer:

x= -1 y = -4

Step-by-step explanation:

x-y=3

y = x-3

substitute in first equation

2x- (x-3)= 2

2x-x +3 =2

x= -1

therefore -1 -y =3

y = -4

Answer 2

Answer:x=-1

y=-4

Step-by-step explanation:

x-y = 3

x=y+3 ------>1

2x-y = 2

2(y+3)-y=2

2y+6-y=2

y=2-6

y=-4

x=y+3

 =-4+3

x=-1
