2. the graph of a linear equations in two variables is represented by two lines and ig the lines intersect at a point ,then that point gives the _____ solution of the two equation .
3. 8th terms of the AP: 7,10,13,____ is
4. If 13x+27y =40 and 27x+ 13y =80 then x+y = _____.
5. the pair of linear equations 2x+3y-9=0 and 4x+6y-18=0 has ____ solution/solutions.
​

Answer 1

Answer:

1 - 2

2 - unique solution (one solution)

3 - 28

4 - x+y 3

5 - infinitely many solution

Step-by-step explanation:

1 - x=0 y=2 put the value you get two ans

2 - a1/a2 not equal b1/b2

3 - a8=a+7d a=7 b=3 put value you get 28

4-

5 = a1/a2=b1/b2=c1/c2

2/4 = 3/6 = -9/-18

1/2 = 1/2 = 1/2
