Question

Solve the following linear equation in one variable.
1.which of the following is not an equation?
(i)8x+3=11. (ii)7k-3=25
(iii)2-11m=-20 (iv)2a+1/2=3/2
(v)6b-2/3=1/2 (vi)n+5/7=4 1/7​

Answer 1

Answer:

Step-by-step explanation:

i) 8x+3= 11

  8x= 11-3

  8x= 8

  x=1

ii) 7k-3=25

   7k= 25+3

   7k= 28

   k= 28/7

   k= 4

iii) 2-11m=-20

   -11m= -20-2

   -11m= -22

   11m= 22

   m= 22/11

   m= 2

iv) 2a+1/2=3/2

   2a= 3/2- 1/2

   2a= 2/2

   2a= 1

   a= 1/2

v) 6b-2/3=1/2

  6b= 1/2+2/3

  6b= 7/6

  b= 7/36

vi) n+5/7=4 1/7​

    n= 29/7-5/7

    n= 24/7

    n= 3 3/7

hope it helps. plz mark as brainliest.
