Question

solve a pair of linear equations graphically 2 X + Y is equals to 6 and 2 x minus y is equals to 2 ​

Answer 1

Answer:

x=2

y=2

Step-by-step explanation:

2(2)+ (2) =6

4+2=6

6=6

2(2)-2=2

4-2=2

2=2

Answer 2

Answer:

X=2;Y=2

Step-by-step explanation:

2x+y=6--(i)

2x-y=2--(ii)

from (i)

y=6-2x---(iii)

substitute (iii) in (ii)

therefore, 2x-(6-2x)=2

                 4x-6=2

                  4x=8

                   x=2

now substitute x in any equation you will get y =2

x=2 in (ii)

2(2)-y=2

4-y=2

y=2

x=2,y=2
