Question

show that the pair of linear equations 2x+y=5 and x+2y=7 are consistent ​

Answer 1

Answer:

hi

Step-by-step explanation:

Answer 2

Answer:

2x+y=5

x+2y=7 then

x=7-2y

put the value of x in first equation

2(7-2y)+y=5

14-4y+y=5

14-5y=5

-5y=5-14

-5y=-9

y=-9/-5

y=9/5

x=7-2y

x=7-2X9/5

x=7-18/5

x=35/5-18/5

x=17/5
