How do you solve x plus y equals 4 and y equals 2X plus 1 by substitution method?
If: x+y = 4 and y = 2x+1 Then: 4-x = 2x+1 => 3 = 3x => 1 = x So by substitution: x = 1 and y = 3
What is 2x plus 3y equals -1 5x-2y plus -12 using substitution?
x = -2 and y = 1
Solve using substitution x minus y equals 2 and x plus y equals -4?
-2
What is the equation for a unit circle when solved for Y?
x2 + y2 = 1x2- x2+ y2= 1 - x2y2 = 1 - x2y =± √(1 - x2)
What is indicated by the occurrence of a false statement such as 0 equals 1 when you solve a system of two linear equations in two variables using substitution?
In that instance, it means that the lines never touch.

What is 2x plus 3y equals -1 5x-2y plus -12 using substitution?
x = -2 and y = 1
Where is the point of intersection of the lines y equals 4x-1 and 3y-8x plus 2 equals 0?
By a process of elimination and substitution the lines intersect at: (1/4, 0)
Solve using substitution x minus y equals 2 and x plus y equals -4?
-2
2x plus y equals 4 and -x plus y equals 1?
Substitution method: y = 1 + x so 2x + (1 + x) = 4, ie 3x = 3 so x = 1 and y = 2
What is the substitution of4x plus 4y equals 16 and y equals 5?
4x+4y=16 y=5 4x+ 20=16 4x=-4 x=-1
What is the equation for a unit circle when solved for Y?
x2 + y2 = 1x2- x2+ y2= 1 - x2y2 = 1 - x2y =± √(1 - x2)
X-2y equals o 9y-4x equals 1 substitution method?
x - 2y=0 so x = 2y 9y - 4x=1 Substituting for x, 9y-4*(2y) = 1 or 9y-8y = 1 so that y = 1 then x = 2y = 2*1 = 2
Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
What is the point of intersection between the lines y equals 4x -1 and 3y -8x plus 2 equals 0?
The point of intersection of the given simultaneous equations of y = 4x-1 and 3y-8x+2 = 0 is at (0.25, 0) solved by means of elimination and substitution.
What is indicated by the occurrence of a false statement such as 0 equals 1 when you solve a system of two linear equations in two variables using substitution?
In that instance, it means that the lines never touch.
What is the substitution method for y equals 5x plus 8 and y equals 10x plus 3?
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
