y = 4x + 1
Select one:
(5, 3)
(-1, 3)
(1, 5)
(-5, -1)

Answer 1

To solve number 1, do
78=8h+22
subtract 22
56=8h
Divide by 8
h=7
Before I go on, did you understand that?

Answer 2

Yes

Answer 3

Alright, I wrote that down so I have it

Answer 4

Ok, for two, let's graph. The answer is where the lines intersect, which is at (1,5).

Answer 5

Anyways, for three, graphing it shows the answer is (3,4)

Answer 6

OK @zeinas.

Answer 7

If asdkfj...doesn't care, please get off the site. This is an abuse.

Answer 8

Yes

Answer 9

go get life @asdijhflakjsdh

Answer 10

On the second problem, both are in the form of y=something.
Put both equations equal to each other and solve for x. Once you have x, you can get y by solving.

Answer 11

Ok I'll go that @dss

Answer 12

*do and I got (1,5)

Answer 13

asdij...I may be old, but I can do math in my sleep. Obviously, I'm a lot smarter than you. And have a larger vocabulary. Get off the site and don't waste our efforts.

Answer 14

yes, (1,5) is right.

Answer 15

Yes

Answer 16

@Yolo4mecuite do you have any other questions, if not can you close this one so we don't have deal with that stupid guy?

Answer 17

y = x + 1
2x + y = 10

with this problem, I'd use substitution. Substitute the 1st equation into the second. You'll have:
2x+(x+1)=10 Now solve for x

Answer 18

Well I actually do but I'll make another post on it. and ok @ds

Answer 19

@dss

Answer 20

ok
