Answer 1

Answer:

Question :-

simplify: 6b−5a+3x−9x+b–a and find the value if x= 3 , a=−2, b=4

Required Answer :-

$6b −5a +3x −9x +b –a$

$= 6(4) −5( - 2) +3(3) −9(3) +4 –( - 2)$

$= 24 + 10 + 9 - 27 + 4 + 2$

$= 34 - 18 + 6$

$= 40 - 18$

$= 22$

Answer 2

Step-By-Step Explanation
6b = 6x4 = 24
-5a = -5 x (-2) = 10
3x = 3x3 = 9
-9x = -9 x 3 = -27

So, 24 - 10 + 9 - 27 +4 - (-2) = 14+ 9 - 27 + 2 = 23 - 25 = -2
And = -2
