Question

Evaluate the following expression: ​

4a – 3b when a = – 3 and b = – 2​

explain how you would get the answer above step by step

Answer 1

To find the answer you plug in the given numbers with their corresponding varible

so 4a - 3b really means
4(-3) - 3(-2) then you solve
4 x -3 = -12
-3 x -2 = 6
-12 - 6 = -18

-18 is your answer

-6

Explanation:

4a-3b

Plug in a b

4(-3)-3(-2)

-12+6=-6
