Question

ill wants to solve the following system using the elimination method:

y = x + 8
y = 3x − 11

What number should the equation y = x + 8 be multiplied by to eliminate x?

1) -1
2) -2
3) -3
4) 3

Answer 1

Equate the 2 formula's together and you will have:

x + 8 = 3x - 11

use algebra to solve the rest

Answer 2

i totally lied its just -3

Answer 3

you want to add <some number> * x+8 and add it to 3x - 11

so 3x + <#> * x = 0?

clearly -3. Sorry for blatantly giving you the answer
