it doesn't equal anything because x and y cannot be combined but if you know what x or/and stand for you could plug those in to answer the problem/question
You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
Y = 2x-5 and Y = 2x plus 7 is a linear system which intersects at points (-2,2)
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
X + ( 2Y - 2X - Y ) is equal to Y - X
It is 3.
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.
y = 5y = -2x + 3Since both of those things are equal to 'y', they're equal to each other.5 = -2x + 3Add 2x to each side:5 + 2x = 3Subtract 5 from each side:2x = -2Divide each side by 2:x = -1The point of intersection is (-1, 5) .
y=2x-3 y=-x-3
The variable 'x' would equal (8-y)/2. The variable 'y' would equal 8-2x.
2x+y=1
(Y = -2x plus or minus any number) is parallel to (Y = -2x + 5) .
The x intercept is where y = 0 y = 2x +5 = 0 2x + 5 = 0 2x = -5 x = -5/2 = -2.5
