Answer 2

Answer:

∴ The value of $A+B-C$ is $2a-5a+1$.

Step-by-step explanation:

• In context with question asked,
• We have to find the value of $A+B-C$.
• It is given that, $A=2a, B=-5a$ and $C=-1$.
• To find the value of $A+B-C$, we have to put the values of $A,B$ and $C$ in the given equation.
• So, the given equation is,

    $A+B-C = 2a+(-5a)-(-1)$

                   = $2a-5a+1$

• ∴ The value of $A+B-C$ is $2a-5a+1$.
