Question

The sum of two algebraic expressions is
17p-llp +4. If one of them is 3p - 9p', find
the other
$7p3 - 11p2 + 4 + 3p3 - 9p2$
​

Answer 1

Answer:

12p + 4

Step-by-step explanation:

We can simplify 3p - 9p into -6p. Now we have an equation

-6p + ? = 17p - 11p + 4

We can add 6p to both sides to find out that

? = 17p - 11p + 4 + 6p

Which simplifies into

? = 12p + 4

So the other expression we are looking for is

12p + 4!
