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 <u>dividing</u>, getting:
-36/4
The ratio of -36 by 4 equals <u>-9.</u>
Therefore...
x = -10
y = -9
The answer is C because my friend has told me it.
Answer:
all of them....take -5, -5*5+8=-25+8,definitely negative....and if -5 is negative, other more extreme options are even more negative
Step-by-step explanation:
Answer:
Elimination:
-4x - 2y = -18 -4x - 2y = -18
x + 3y = 8 | ×4 ------> <u> 4x + 12y = 32 </u> +
10y = 14
y = 1,4
x + 3y = 8
x + 3(1,4) = 8
x + 4,2 = 8
x = 3,8
