Question

The solution of 8-7x=1 is x =
21

​

Answer 1

7x=1/8 by translating LHS TO RHS and by translating 7 to RHS it turns to 1/8/7 as 7 comes up it turns to 7/8 therefore answer =7/8

Answer 2

8 - 7x = 1 if x = 21

8 - 7(21) = 1

8 - 141 = 1

-153 ≠ 1

Correct answer :-

8 - 7x = 1

-7x = 1 - 8

-7x = -7

cancel minus we get,

7x = 7

x = 7/7

x = 1

there x = 1 I hope it helps you have a nice day :-):-)
