Question

The pair of equation x = 2 and y + 7 = 0

Answer 1

Answer:

X - Y equal to 9 it can be written like this also

Answer 2

Answer: one solution

Step-by-step explanation:

x=2 can be written as x+0y-2=0 and y+7=0 can be written as  0x+ y +7=0

now, coefficient of x in first equation is 1 and second equation is 0

so, x1/x2=1/0

coefficient of y in first equation is 0 and second equation is 1

so,y1/y2=0/1

as we can see 1/0 is not equals to 0/1

so, x1/x2 is not equal to y1/y2 which means the pair of equations have only one solution
