It is 3.
The variable 'x' would equal (8-y)/2. The variable 'y' would equal 8-2x.
The closest to a solution you can come is:2x + y = 39
-1
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
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.
X + ( 2Y - 2X - Y ) is equal to Y - X
It is 3.
The variable 'x' would equal (8-y)/2. The variable 'y' would equal 8-2x.
The closest to a solution you can come is:2x + y = 39
4
4x+3y-2x+y 4x-2x+3y+y 2x+4y Taking out 2 common 2(x+2y) Hence the required answer is 2(x+2y)
-1
you need to know the x or y value
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
Collecting like terms they are equal to: 2x+6y
x = -2 and y = 3
