Identity
An identity is an equation that is true for all values of the variables. For example:
(x+y)^2=x^2+2xy+y^2
The above equation is true for all possible values of x and y, so it is called an identity.
Strictly speaking we should use the "three bar" sign to show it is an
identity as shown below. But it is very common to use the equal sign.
The best and most correct answer among the choices provided by the question is the first choice. The first step to do during the substitution method is to s<span>olve the top equation for x. </span><span>I hope my answer has come to your help. God bless and have a nice day ahead!</span>

Answer:
Yes I agree with Andre's method he did it the correct way
Step-by-step explanation:
Answer:
-3 / 2
Step-by-step explanation:
- 5x - 6 = 3x - 9
- 5x - 6 + 6 = 3 x - 9 + 6
- 5x = 3x - 3
- 5x - 3x = 3x - 3 - 3x
- 2x = - 3
- 2x / 2 = -3 / 2
- The X = -3 / 2
