Answer:
To show that an equation is an identity: Start with either side of the equation and show that it can algebraically be changed into the other side. Or start with both sides of the equation and show that they both can be changed into the same algebraic expression.
Step-by-step explanation:
<span>2x − 3y − z
</span><span> x = −2,
</span><span> y = 3,
</span><span> z = −2
What we must do is replace the values given in the equation. We have then replacing:
</span> 2*(-2) - 3*(3) - (-2) = -11
The answer is -11
