The expression "13 plus y" represents the sum of 13 and a variable y. It is written in algebraic notation to denote a mathematical operation. The result of this expression will depend on the specific value assigned to the variable y.
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
2x + y = 5 so y = 5 - 2x; This gives x - 3(5 - 2x) = 13 ie x + 6x = 13 + 15 so x = 4 and y must be -3
If you mean y+2 = -3(x -5) then y = -3x+13 whereas -3 is the slope and 13 is the y intercept
If you mean: y=6+x/ x=7 Then that is the equation for a line. Put in any number for "x" and "y" will always be 6 more than that. In this case, y=13
xy + x + y + 1 = (x + 1)(y + 1).
-y + 7 = 13 -y = 6 y = -6
-13
If: -11x+y = 13 Then: y = 11x+13 whereas 11 is the slope and 13 is the y intercept
y = (13 - 3x)/2 and that cannot be simplified further.
x intercept: -4 1/3 y intercept: 13
y=4
-9
If you mean: y = 4x-2 and y = x+13 then x = 5 and y = 18
(2, 7)
yes.
It is 5200300.
It is an equation and the value of y is 18
