Question

solve the system using an algebraic method

x - y = 5
2x - 4y + 6 = 0

Answer 1

are those two together

Answer 2

yes

Answer 3

So without x and y it would be 2 - 4 + 6

Answer 4

answer choices r ( 2,-3) (3,2) infinite number of points or no solution

Answer 5

First you multiply the top equation by -2 to cancel out the x variable

Answer 6

so.... what is it then

Answer 7

umm (2, -3) ?

Answer 8

no multiply the top equation by -2 then it would be

-2x+2y=-10
2x-4y+6=0

Answer 9

Then you would add the equations together so....
-2y+6=-10

Answer 10

This is interesting.

Answer 11

A. ( 2,-3) B. (3,2) C. infinite number of points D. no solution these r my only choices

Answer 12

Then solve the equation

-2y+6=10

Answer 13

-2

Answer 14

i mean -2y+6=-10

Answer 15
