Question

2. Simplify: 91 - 3(7)º
3. Find the value of a' and 'b
'a
5+23
VE-25
a-b
$\sqrt{6}$
​

Answer 1

Answer:

5A -7(B + 3) = 2

5A-7B-21=2

5A-7B=23

As A and B are positive intergers and from answer choices we know that A>B. lets do trial and error:

Lets say A=5, then B=-ve. not possible

Say A=6, then B=1

Therefore, A-B=5
