Question

The pair if equation x+y=1 and2x+2y=2has which solution

Answer 1

Answer:

this pair of equations has infinite no. of solutions. The solution of this pair of equations is dependent (consistent).

Answer 2

Answer:

Step-by-step explanation:

Given eqn.

x+y=1 .........(1)

2x+2y=2.........(2)

Multiplying simaltaneous eqn (1) by 2 & eqn(2) by 1

2x+2y=2...........(3)

2x+2y=2...........(4)

(Substracting eqn. 1-eqn. 2)

2x+2y=2

-2x+2y=2

 x        =0

substituting x=0 in eqn.1

2(0)+2y=2

0+2y=2

2y=2

y=2÷2

y=1

answer = (x,y) =(0,1)
