How do you solve 2x plus y equals 4?
It depends on what you mean by "solving", with two unbound variables (x and y) you will be able to produce a two-dimensional x/y plot: 2x+y=4 means y=4-2x
How do you solve 2x-y equals 4 and 2y equals 4x-6 using the substitution method?
2x-y = 4 and 2y = 4x-6 pick either equation and solve for one of the variables the first equation: y = -4 + 2x plug in the value of variable you solved for into the other equation 2(-4 + 2x) = 4x -6 then solve -8 + 2x = 4x-6 -2 = 2x x= -1 then plug in the value you have found into either original equation to find the value of the other variable 2(-1) - y = 4 -2 - y = 4 -y = 6 y = -6
How do you solve -2x equals y-6?
4
How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
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
How do you solve 2x plus y equals 4?

What are the intercepts of the equation 2x 5y 20?
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
How do you solve 2x-y equals 4 and 2y equals 4x-6 using the substitution method?
2x-y = 4 and 2y = 4x-6 pick either equation and solve for one of the variables the first equation: y = -4 + 2x plug in the value of variable you solved for into the other equation 2(-4 + 2x) = 4x -6 then solve -8 + 2x = 4x-6 -2 = 2x x= -1 then plug in the value you have found into either original equation to find the value of the other variable 2(-1) - y = 4 -2 - y = 4 -y = 6 y = -6
Y plus 2x equals 0 solve for y?
y= -2x
How do you solve -2x equals y-6?
4
How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
What is Solve By Subtitution y0.5x plus 2 -y-2x plus 4?
When using substitution the answer to y0.5x plus 2 -y-2x plus 4 is y = -2 (x-1.
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 two numbers have the sum of 22 and the difference is 4?
X + Y = 22 X - Y = 4 add equations: 2X = 26 solve X X = 13 solve Y Y = 9
Where does 2x plus y equals 0 and x plus y equals -4 intersect?
If: 2x+y = 0 and x+y = -4Then: x = 4 and y = -8Possible steps:2x + y = 0x + y = -4Subtract the two equations:x = 4Plug x back in to one equation and solve for y:4 + y = -4y = -8
How do you solve y equals y equals 2x-1 y equals 5x-13?
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
What is X - 2y equals -4 and 2x - y equals 1?
x - 2y = -4 2x - y = 1 To solve this system of equations, I used matrices, and got x = 2 and y = 3.
