A variable is a number that isn't fixed, it can be anything. So in this situation x and y are the variables.

2x plus y 8?
It may be a linear function in two variables.
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
Simplify the variable expression 2x plus y plus 5 - 3?
The expression goes like this: 2x+y+5-3. x and y are variables so we cannot perform unless we have a linear or simultaneous or as such equations.But operation can be performed if like terms are present, but in your problem the answer will be: 2x+y+2
Solving for y -2x plus - 40y equals 10?
you need 2 equations to solve for 2 variables
Y 2x-5 Y 2x plus 7?
Y = 2x-5 and Y = 2x plus 7 is a linear system which intersects at points (-2,2)
What are the variables for 2x - 5y plus 3z equals -1?
x, y and z are the variables.
2x plus y 8?
It may be a linear function in two variables.
Factor 2x squared plus 2x plus xy plus y?
4

How many solutions does 2x-y equals 8 and x plus y equals 1 have?
2x - y = 8 x + y = 1 These are your two equations. They will have two solutions since you have two variables. The solutions are x=3 and y=-2
Y plus 2x equals 0 solve for y?
y= -2x
What is the slope and y intercept for the line y equals -2x plus 8?
Y = - 2X + 8 Just read it off the function, aY = mX + C - 2 = m(slope) 8 = Y intercept You can also zero out the variables in turn
Y equals 2x plus 1?
Y = 2x + 1
What do x and y equal in 5y equals 2x plus 6?
It is not possible to solve a single linear equation in two variables.
