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

​
LHS
RHS

​

Answer 1

Answer:

8 - 7x = 1

8 = 1 + 7x

8 - 1 = 7x

7 = 7x

7÷7 = x

1 = x

Answer 2

SOLUTION:

$\\ \\ \\ to \: prove \: lhs = rhs \: \\ \\ \\ = > 8 - 7x = 1 \\ \\ \\ = - 7x = 1 - 8 \\ \\ = > - 7x = - 7 \\ \\x = 1 \\ \\ hence \: \: lhs \: \: = \: \: rhs \: \: \: (proved)$

NOTE:

• ANY NUMBER WHEN IT GOES AFTER THE "=" SIGN REVERSES ITS SIGN I.E.

(-VE) ----> (+VE)

AND

(+VE) -----> (-VE)
