Answer:

d)
x=5

Go to station 10

Explanation:


-\left(1+7x\right)-6\left(-7-x\right)=36

Expand:


-1-7x+42+6x=36


-x+41=36

Subtract 41 from both sides:


-x+41-41=36-41


-x=-5

Divide both sides by -1:


(-x)/(-1)=(-5)/(-1)


x=5

Given : A linear equation is given to us . The equation is - ( 1 + 7x ) - 6 ( -7 - x ) = 36 .

To Find : The value of x .

Solution : The linear equation given to us is - ( 1 + 7x ) - 6 ( -7 - x ) = 36 . Let's simplify this step by step to find the value of x .

⇒ - ( 1 + 7x ) - 6 ( -7 - x ) = 36


\red{\underline{\tt Step \:1- Open \:the\:brackets.}}

⇒ - 1 - 7x +42 + 6x = 36 .


\red{\underline{\tt Step \:2- Group\: variables\:and\: constant\: terms.}}

⇒ -7x + 6x -1 +42 = 36 .


\red{\underline{\tt Step \:3- Transfer \: variables\:on\:one\: side\:\&\: constant\:terms\;on\: other\: side..}}

⇒ -x = 36 - 41

⇒ - x = -5

x = 5 .


\Large\boxed{\purple{\bf Value\:of\:x=5}}
