Question

Need the steps too this

Answer 1

The value of x  is 9.

We have :    - 25 = 7 - (5x - 13)

We have to find the value of x.

If f(x) = g(x), than what do you understand by true solution of this equation?

The true Solution of the equation is the value of x for which LHS = RHS.

For example - if  ax + b = cx + d , then

ax - cx = d - b

x = $\frac{d-b}{a-c}$   is the true solution of the equation.

In the question given -

- 25 = 7 - (5x - 13)

- 25 = 7 - 5x + 13

5x = 45

x = 9

Hence, the value of x for which LHS = RHS is 9.
