X = 2 and Y = 3.
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
2x + 2y=-2 (Dividing it by two)x+y=-1 (By transposition)x=-y-1
x - 2y = -4 2x - y = 1 To solve this system of equations, I used matrices, and got x = 2 and y = 3.
y=(-1) x=(2)
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.
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
get it to y= -2y = 1 - 2x y = x - 0.5
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).

If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
2x + 2y=-2 (Dividing it by two)x+y=-1 (By transposition)x=-y-1
x - 2y = -4 2x - y = 1 To solve this system of equations, I used matrices, and got x = 2 and y = 3.

y=-3/2x + 1/2
The equation "x plus 2y equals 5" is: x + 2y = 5 2y = 5 - x y = 5/2 - 1/2x y = -1/2x + 5/2
x= 3 and y = 2
