Question

If 7 ( x + 5 ) = -7 ( x + 5) then x =

Answer 1

Answer:

5

Step-by-step explanation:

$7(x + 5) = - 7(x + 5) \\ =)7x + 35 = - 7x - 35 \\ = )7x + 7x = - 35 - 35 \\ = )14x = - 70 \\ = )x = - 5$

Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $7(x+5)=-7(x+5).$

              To find:- Value of the expression.

              Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we will Identify the variables and constants.

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        By using the transposition method.

        we get,

                  $7(x+5)=-7(x+5)\\=>7x+35=-7x-35\\=>7x=-7x-70\\=>14x=-70\\=>x=\frac{-70}{14}\\=>x=-5$

      Hence we will get the value $x=-5.$
