X=-2-8

3x-4y=6

What is the answer for

Answer: (x, y) = (-10, - 9)

Step-by-step explanation:

(By replacement method ...)

1 - x = - 2-8 it's the same thing as x = - 10.

2 - Replace the given value of x in equation 3x - 4y = 6

Replacing ...

3 * (-10) - 4y = 6

3 - Then, Multiply 3 by - 10;

4) Move - 30 to the right side of the equal sign, getting: 6 + 30.

-4y = 36

5) Multiply by - 1

-4y * ( - 1) = 36 * ( - 1) is equal to 4y = - 36

6) The four is multiplying the y, so pass the four dividing, getting:

-36/4

The ratio of - 36 by 4 equals - 9.

Therefore ...

x = - 10

y = - 9
