8 0

Answer:

x= -1, y= 1

Step-by-step explanation:

2x + 6y = 4.........(1)

8x - 5y = 45........(2)

multiply equation (1) by 4

8x + 24y = 16......(3)

subtract equation (3) by (2)

29y = 29

y = 1

then substitute y=1 in equation (1)

2x + 6(1) = 4

solving for x

x = -2/2 = -1

ect the best answer for the question. 3. Rewrite the equation x + y + 3 = –2x + 4y + 18 into standard form (ax + by = c). A. 3x
trapecia [35]

Answer:

B

Step-by-step explanation:

To rewrite the equation x + y + 3 = -2x + 4y + 18, first combine like terms.

x + y + 3 = -2x + 4y + 18

3x - 3y + 3 = 18

3x - 3y = 15

This is the standard form.

It can also be simplified by dividing each term by 3 to x - y = 5.
