3. Combine terms: 12a + 26b -4b – 16a

 

(a) 4a + 22b,

(b) -28a + 30b,

(c) -4a + 22b,

(d) 28a + 30b.

First we simplify the equation:

12a+26b-4b-16a

=-4a+22b

Ad thus (c)-4a+22b is our final answer

Very similar approach:

 

\(12a + 26b -4b – 16a \implies 12 a - 16 a + 26 b - 4 b \implies -4a+22b\)
