Question

If a=2 and b=3, Find the value of a) 2a – 3b b) 5 – 2ab​

Answer 1

A=2+2 as a is equal to 2 so 2+2=4 and 3+3 as b=3 so 3+3=6 so 6-4 = 2 is the answer
B=5-2+2+3 as a=2 b=3 so 2+2+3=8 so 8-5=3 is the answer

Answer 2

Answer:

The value of (a) 2a -3b is - 5 and (b) 5 - 2ab is _7

Step-by-step explanation:

Given:

a=2 , b = 3

(a) 2a - 3b=2 × a - 3 × b

putting the value of a and b we get,

                 = 2 × 2 - 3 × 3

                 = 4 - 9

                 = - 5

(b) 5 - 2 a b =5 - 2 × a × b

Putting the value of a and b we get,

                   = 5 - 2 × 2 × 3

                    = 5 - 12

                   = - 7
