Question

X=Y ,Y=Z is a solution of the line equation
a) x+2y=7
b)5x+2y=7
c)x+y=7
d)5x+y=7​

Answer 1

Answer:

y+2z =7

5y +2z=7

y+z=7

5y+z=7

Answer 2

Step-by-step explanation:

but dear...what is the value of x and y.

if x = 5 and y = 2 than the ans. is

a) x + 2y = 7

:- 5 + 2(2) = 7

5 + 4 = 7

9 ≠ 7

b) 5x + 2y = 7

:- 5(5) + 2(2) = 7

25 + 4 = 7

29 ≠ 7

c) x + y = 7

:- 5 + 2 = 7

7 = 7

d) 5x + y = 7

:- 5(5) + 2 = 7

25 + 2 = 7

27 ≠ 7.

so option b is correct....hope this answer helps you dear....and take care and give me multiple thanks too! enjoy ur day
