Solution for f(x)=f(x-1)+100x equation:


Simplifying
f(x) = f(x + -1) + 100x

Multiply f * x
fx = f(x + -1) + 100x

Reorder the terms:
fx = f(-1 + x) + 100x
fx = (-1 * f + x * f) + 100x
fx = (-1f + fx) + 100x

Add '-1fx' to each side of the equation.
fx + -1fx = -1f + fx + -1fx + 100x

Combine like terms: fx + -1fx = 0
0 = -1f + fx + -1fx + 100x

Combine like terms: fx + -1fx = 0
0 = -1f + 0 + 100x
0 = -1f + 100x

Solving
0 = -1f + 100x

Solving for variable 'f'.

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

Add 'f' to each side of the equation.
0 + f = -1f + f + 100x
Remove the zero:
f = -1f + f + 100x

Combine like terms: -1f + f = 0
f = 0 + 100x
f = 100x

Simplifying
f = 100x
