Question

-3x – y = 1 x + 6y = 11...what are the 2 answers?

Answer 1

Are they two separate equations?

Answer 2

yes formated like this (___,___)

Answer 3

Is it suppose to be -3x-y=1
And. x+6y=11

Answer 4

yes

Answer 5

If it is how I showed it then you will need to multiply either the top or bottom by a number to cancel out one of the letters. Example multiply the entire bottom row by the and then add the two rows together.

Answer 6

Sorry multiply bottom by three

Answer 7

whats the answer?

Answer 8

3(-x+6y=11)

Answer 9

but there is 2 seperate answers

Answer 10

a= im hungry

Answer 11

-3x – y = 1 x + 6y = 11 can be formulated into these 2 simultaneous equations:

-3x - y = 11
x + 6y = 11

There are two ways to do this, but I'll pick the easier one: substitution.
Firstly, make either variable the subject of one equation. I'll pick y and the first equation. Add y to both sides then subtract 11 from both sides to get y = -3x - 11. Then substitute this newfound equation into the second equation:
x + 6(-3x-11) = 11
Process 6(-3x-11) and get x - 18x - 66 = 11.
Add 66 to both sides and simplify x to get -17x = 77.
Now divide -17 on both sides to get x = -77/17.

Substitute x = -77/17 into x + 6y = 11 and continue to find y.
