Question

Solve by elimination
4x - y = 29

6x - 2y = 40

Answer 1

Do i multiply by 2 to get the y's to be the same

Answer 2

just multiply first equation bu -1

Answer 3

kk

Answer 4

-2
sorry

Answer 5

-8x-2y=-58

Answer 6

2 by -24 is -48

Answer 7

then add two equation to get rid of -2y

Answer 8

??????? i'm so confused one person plz

Answer 9

-8x=-58
6x=40

Answer 10

-2x=-18
x=9

Answer 11

????

Answer 12

-2(4x - y = 29)
6x - 2y = 40
-----------------

-8x + 2y = -58
6x - 2y = 40
-----------------

-2x + 0y = -18

x = 9

now substitute x into any of the two equations to find y.

6(2) -2y = 40

12 - 2y = 40

-2y = 40 - 12

-2y = 28

y = -14

Answer 13

thx for the help

Answer 14

Sorry,made a mistake.

6(9) - 2y = 40

54 - 2y = 40

-2y = -14

y = 7

Answer 15

Check to see if x = 9 and y =7 are solutions to your problem.

Plug it into 4x - y = 29

4(9) - 7 = 29

36 - 7 = 29

29 = 29
