Question

4. x=5, y=2 is a solution of the linear equation
(a) x + 2y = 7 (b) 5x+2y=7 (c)x+y=7
(d) 5x+y=7​

Answer 1

Answer:

(a) x + 2y = 7 x=5,y=2

puting value of x and y in equation

5+2(2)=7

5+4=7

9≠7   ∵ it is not solution

(b) 5x+2y=7 puting value of x and y on equation

5(5)+2(2)=7

25+4=7

29≠7  ∵ it is not solution

(c) x+y=7 (similer)

5+2=7

7=7 ∵ it is solution

(d) 5x+y=7  (similler)

5(5)+2=7

25+2=7

27≠7  ∵ it is not solution
