Question

7( x -7)+ 6( 7 - x) = 1

Answer 1

Step-by-step explanation:

Q:-

7( x -7)+ 6( 7 - x) = 1

A :-

step 1 :-

$7(x - 7) + 6(7 - x) = 1$

$7x - 49 + 6(7 - x) = 1$

step 2 :-

$7x - 49 + 6( - x + 7) = 1$

step 3 :-

$7x - 49 - 6x + 42 = 1$

step 4 :-

$7x - 7 - 6x = 1$

step 5 :-

$1x - 7 = 1$

$x - 7 = 1$

Add 7 to both sides of the equation

$x - 7 + 7 = 1 + 7$

$x = 8$
