Question

Simplify the given expression and find its value
if 𝑎 =−1, 𝑏 =−2:
2𝑎 – 2𝑏 – 4 – 5 + 𝑎

Answer 1

In this question we have to find the value of an expression.
We can directly put the values.
a = -1, b = -2
Putting values in 2a - 2b - 4 - 5 + a
(2 × -1) - (2 × -2) - 4 - 5 + (-1)
= -2 + 4 - 4 - 5 - 1 = -8
