Combine terms: 12a + 26b -4b – 16a.

(a) 4a + 22b,

(b) -28a + 30b,

(c) -4a + 22b,

(d) 28a + 30b.

$\huge\boxed{\fcolorbox{red}{orange}{Solution}}$

12a+26b-4b-16a

=>12a-16a+26b-4b

=>-4a+22b.

Hence,Option c(-4a + 22b) is correct..

Answer 2

Answer:

5(x−1)−2(x+8)=9

5(x−1)−2(x+8)=95x−5−2x−16=9

5(x−1)−2(x+8)=95x−5−2x−16=95x−2x−5−16=9

5(x−1)−2(x+8)=95x−5−2x−16=95x−2x−5−16=93x−21=9

5(x−1)−2(x+8)=95x−5−2x−16=95x−2x−5−16=93x−21=93x=9+21

5(x−1)−2(x+8)=95x−5−2x−16=95x−2x−5−16=93x−21=93x=9+21x=30÷3

5(x−1)−2(x+8)=95x−5−2x−16=95x−2x−5−16=93x−21=93x=9+21x=30÷3x=10

5(x−1)−2(x+8)=95x−5−2x−16=95x−2x−5−16=93x−21=93x=9+21x=30÷3x=10
