R(x)=400x-80x

Solution for R(x)=400x-80x equation:

Simplifying
R(x) = 400x + -80x

Multiply R * x
xR = 400x + -80x

Combine like terms: 400x + -80x = 320x
xR = 320x

Solving
xR = 320x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-320x' to each side of the equation.
-320x + xR = 320x + -320x

Combine like terms: 320x + -320x = 0
-320x + xR = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-320 + R) = 0

Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:

Simplifying
x = 0

Solving
x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying
x = 0
Subproblem 2
Set the factor '(-320 + R)' equal to zero and attempt to solve:

Simplifying
-320 + R = 0

Solving
-320 + R = 0

Move all terms containing x to the left, all other terms to the right.

Add '320' to each side of the equation.
-320 + 320 + R = 0 + 320

Combine like terms: -320 + 320 = 0
0 + R = 0 + 320
R = 0 + 320

Combine like terms: 0 + 320 = 320
R = 320

Add '-1R' to each side of the equation.
R + -1R = 320 + -1R

Combine like terms: R + -1R = 0
0 = 320 + -1R

Simplifying
0 = 320 + -1R
