$x = 4$ $x=4$

Remove the brackets first. Be Careful with the negative signs

$- (2 + 7 x) - 6 (- 7 - x) = 36$ $-( 2 + 7x ) - 6( - 7- x ) = 36$

$- 2 - 7 x + 42 + 6 x = 36 \leftarrow$ $-2-7x +42+6x = 36" "larr$ collect like terms and re-arrange,

$40 - 36 = x \leftarrow$ $40-36 = x" "larr$ move the variables to the RHS

$4 = x$ $4 = x$

How do you solve −(2+7x)−6(−7−x)=36-( 2 + 7x ) - 6( - 7- x ) = 36?
