If x-y equals -3 and 2x plus y equals 12 then what does x and y equal?

x - y = -3
2x + y = 12 (add both equations)
3x = 9 (divide by 3 to both sides)
x = 3
x - y = -3 (replace x with 3)
3 - y = -3 subtract 3 to both sides)
-y = -6 (multiply by -1 to both sides)
y = 6
The solution of the system of the equations is (3, 6).

Equation 2X plus 5 equals 17?
2x must equal 12 so x is 6.
What is the answer to -2x plus 5y equals 12?
2x +n5y=12
Does 12 plus 20 equals 10 equal to 4x plus 14 equals 2x 30?
I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
Does x plus 4 and x plus 5 equal x plus x plus 12?
no...why would it.... it equals 2x+9
What is the answer of 2x plus 10 equals 12?
2x+10=12 2x=2 x=1
What is 4(2x plus 3) equal?
It equals 8x+12
Equation 2X plus 5 equals 17?
2x must equal 12 so x is 6.
Y equals 2 2x plus 6y equals 22?
Since y = 2, 2x + 6y is the same as 2x + 12. Because 2x + 12 = 22, 2x = 10. If 2 Xes are equal to ten, then 1 X is equal to 5.
What is the answer to -2x plus 5y equals 12?
2x +n5y=12
Does 12 plus 20 equals 10 equal to 4x plus 14 equals 2x 30?
I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
Does x plus 4 and x plus 5 equal x plus x plus 12?
no...why would it.... it equals 2x+9
What is 4x plus 1 equals 2x plus 12 equals?
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
What is the answer of 2x plus 10 equals 12?
2x+10=12 2x=2 x=1
What is 2x plus 9 equals 4x plus 5 equal?
X equals 2 :)
What is the answer to 5x equals 3x plus 12?
2x-12
3x - 12 equals -2x plus 23 equals?
3x - 12 = -2x + 235x = 35 so x = 7
What does y equals 2x plus 3 equal?
It equals to the equation of a straight line.
