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.

How do i solve for x with an equation that says 19 = x - 3
Anvisha [2.4K]

Answer: x = 22

Step-by-step explanation: Since x is unknown, we want to isolate it and determine what it equals. We know that x - 3 gives us 19, but we don't want to know what x - 3 is, just x. So we can add three to both sides of the equation, to get our answer and keep it balanced. As a result, we get x = 22

Thanks for your answer♡♡.​
Crazy boy [7]

Answer: -1

Step-by-step explanation:

(2x(x+1)+2x(x-3))/(4x(x-3)(x+1)) = 2x/((x-3)(x+1))

(2x-2)/(2) = 2x

x-1 = 2x

-1 = x
