Question

Pls help will mark brainliest
4x+2y=6
x-3y=5
SOLVE BY ELIMINATION METHOD PLS

Answer 1

Answer:

y=-1

Step-by-step explanation:

The first step to solving this problem is to write it out like this-->

4x+2y=6

x-3y=5    

Next you want to eliminate the X's or the Y's, I chose to elininate the X's-->

4x+2y=6

-4(x-3y=5) [You MUST distribute the -4 to each of the numbers in the equation]

Then you get--->

4x+2y=6

-4x+12y=-20 Then you add them top to bottom--->

0x+14y=-14 [At this point you dont have to write the X]Next you solve for y-->

14y=-14 Divide both sides by 14, in order to get the y by itself-->

y=-1 And theres your answer hope it helps :D

Answer 2

we have the 2 equations

4x + 2y = 6 → (1)

x - 3y = 5 → (2)

multiply (2) by 4

4x - 12y = 20 → (3)

(3) - (1) to eliminate the terms in x

- 14y = 14 ( divide both sides by - 14 )

y = - 1

substitute y = - 1 into (1) and solve for x

4x - 2 = 6 ) add 2 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

solution is x = 2, y = - 1
