Question

Hurry ASAP!!!!! I only need help with number 6 please explain how you get the answer to! The instructions for his equation is: subtract by changing the signs of the subtrahend and combining as in addition!

Answer 1

-ax + 6by + 10

Explanation:

(2ax + 3by + 5) - (3ax - 3by - 5)

Subtrahend is the value AFTER the subtraction sign. So in this example the subtrahends enclosed in the 2nd bracket are 3by and 5.

So subtracting by changing the signs of the subtrahends:

= 2ax + 3by + 5 - 3ax + 3by + 5

Collecting like terms:

= 2ax - 3ax + 3by + 3by + 5 + 5

Combining like terms:

= -ax + 6by + 10
