It is a linear equation in the variable r.
5x+4y=20 is technically the equation of a line. A more familiar representation of the line is in "y equals" notation. This simply means that the y variable has been isolated (this notation is usually required for graphing calculators). To get the equation in y equals notation, simply isolate the y variable: 5x+4y=20 4y=(-5)x+20 y=((-5)x+20)/4
Ok this equation is 20 = 0.004 x N, yes? Rearrange for the variable 'N' to get 20/0.004 = N, N = 5000. Not hard.

First you get the variables on one side and the constants on the other. -2x = 14 Then you divide by -2 to get the variable alone. x = -7
The variable is k.
It is a linear equation in the variable r.
Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2

It is an equation and the value of x is 20
-2t = -10
5x6 = 30 -10 = 20.
