Question

Simplify
Q1) 3x + 5y - x + 2y
Q2) 3g + 5h + 4g - 2h
Q3) 4p + 2p - 3p

Answer 1

3x-x+5y+2y

Explanation:

after putting the like terms together then add or subtract as given.

2x+7y as our final answer.

3g+4g+5h-2h

7g+7h

since our final answer is factorisable we write our final answer as 7(g+h)

4p+2p-3p

since our terms are all alike we just go directly to adding and subtracting.

3p as our answer

Answer 2

1) 2x+7y

2) 7g+3h

3) 3p

Explanation:

Combine like terms.

3x - (1)x = 2x, and 5y + 2y = 7y, so you could say 2x + 7y.

I hope this helps :)
