Question

Can you please help me?!

Answer 1

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 .

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

Answer 2

Answer:

d) $x=5$

Go to station 10

Step-by-step 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:

$\frac{-x}{-1}=\frac{-5}{-1}$

$x=5$
