Answer 1

Answer:

$- 7x - 15 = - 4$

$- 7x + 4x = 15$

$- 3x = 15$

x = - 15/3

$x = - 5$

Ans. -5

Hope it helps.

Answer 2

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

              Given data:- $-7x-15=-4x.$

              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 wi.ll 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,

                  $-7x-15=-4x\\=>-7x+4x=15\\=>-3x=15\\=>x=\frac{15}{-3}\\=>x=-5 .$

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