Need help quickly its hard
kaheart [24]

Answer:

1-3x+8y

Step-by-step explanation:

Multiply y and 2

Multiply y and 1

The y just gets copied along.

2*y evaluates to 2y

Multiply x and 4

Multiply x and 1

The x just gets copied along.

The answer is x

4*x evaluates to 4x

2*y-4*x evaluates to 2y-4x

The answer is 2y-4x+8

2*y-4*x+8 evaluates to 2y-4x+8

Multiply y and 6

Multiply y and 1

The y just gets copied along.

The answer is y

6*y evaluates to 6y

2y + 6y = 8y

The answer is 8y-4x+8

2*y-4*x+8+6*y evaluates to 8y-4x+8

-4x + x = -3x

The answer is -3x+8y+8

2*y-4*x+8+6*y+x evaluates to -3x+8y+8

8 - 7 = 1

The answer is 1-3x+8y

2*y-4*x+8+6*y+x-7 evaluates to 1-3x+8y

4k – 3 = -2k + 3 help me please lol
hoa [83]

Answer: k=1

Step-by-step explanation:

4k-3=-2k+3

4k=-2k+3

           +3

4k=-2k+6

take the -2k and change the sign and add to 4k

4k=6

2k

6k=6
