5y - 3y = 18 2y = 18 y = 18/2 y = 9
If: 3y+8 = 5y-20 Then: 3y-5y = -20-8 So: -2y = -28 And: y = -28/-2 => y = 14
-2 = 3y-18-5y 16=3y-5y 16=-2y y=-8
5y+14+y = 3y-7 5y+y-3y = -7-14 3y = -21 y = -7
The median is the value that lies halfway along the series when arranged in ascending or descending order. When arranged in ascending order : y, 2y, 3y, 4y, 5y : the median is 3y. If 3y = 27 then y = 9.

5y-3y = 2
5y - 3y = 18 2y = 18 y = 18/2 y = 9
If: 3y+8 = 5y-20 Then: 3y-5y = -20-8 So: -2y = -28 And: y = -28/-2 => y = 14
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
-2 = 3y-18-5y 16=3y-5y 16=-2y y=-8
5y+14+y = 3y-7 5y+y-3y = -7-14 3y = -21 y = -7
The median is the value that lies halfway along the series when arranged in ascending or descending order. When arranged in ascending order : y, 2y, 3y, 4y, 5y : the median is 3y. If 3y = 27 then y = 9.
2x + 3y - x + 5y combine the like terms 2x - x + 3y +5y simple arithmetic x + 8y
I understand this to be 4x + 3y - 5x + 2y. -x + 5y
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
