Question

**MEDAL**
Can somebody explain this to me? Is there a specific formula for this?

Answer 1

There isn't a special formula or anything. This is a problem talking about two lines given by the two equations. And the question is basically asking about where they intersect.

Answer 2

put first equation in second to find value of x

then using that value determine the value of y

Answer 3

Following the insert rule, is the answer B?

Answer 4

looks good to me!

Answer 5

I basically did
4(1/2) + 2(3/2) = 5

Answer 6

No formula,you need to arrange them and add/subract
-9x+y=-3 (-2)
4x+2y=5

18x-2y=6
4x+2y=5
========
22x=11
x=11/22
x=1/2


now use the value of x in any original equation to find y

4(1/2)+2y=5
2+2y=5
2y=5-2
2y=3
y=3/2

Answer 7

You need to equal y or x to solve.

Answer 8

@NobodySpecial but you need to make sure that that point is in both equations. But yes that's correct.

Answer 9

Thank you everyone for your help! :)

Answer 10

Yw. :)
