(3p-10q)-(p-8q)
I can’t figure this out !!!

Answers

Answer: 2p - 2q

Step-by-step explanation:

(3p-10q)-(p-8q) is simply an algebraic expression.

To solve it, you first open the brackets

i.e 3p - 10q - p + 8q (the minus sign between the brackets have multiplied the next minus sign, so it becomes plus sign)

Now, collect the like terms of i.e common terms

= 3p - 10q - p + 8q

= 3p - p - 10q + 8q

= 2p - 2q

Thus, the final expression is 2p - 2q since it cannot be further simplified.
