Simplify:<br> 3x + 7y - 2p + 7x - y
natali 33 [55]

Answer:

10x + 6y - 2p

Step-by-step explanation:

Combine Like Terms

First combine the x's

3x + 7y - 2p + 7x - y

10x + 7y - 2p - y

Then the y's

10x + 7y - 2p - y

10x + 6y - 2p

And that's it

1. Mckayla is using elimination to solve the
Arturiano [62]
By using the elimination method, you would essentially add the two equations together by combining like terms. normally this would require manipulation however this equation doesn't because the y is already opposites of each other. (a negative and positive value of the same number i.e. -2 and 2)

so add the two equations together and you're left with 2x = 16, (they y's cancelled each other out) then divide two on both sides to get x = 8

now, use that x value in either equation (it doesn't matter which), we can use -3x+2y=-26

plug it in to get -3(8) + 2y = -26
which is then -24 + 2y = -26
add 24 to both sides: 2y = -2
divide 2 on both sides: y = -1

now knowing x=8 and y= -1 we can say that the answer is (8,-1)

hope this helps!!
