F (x) = lx+4l+3 how do u do it

implifying

f (x) = lx + 4l + - 3

Multiply f * x

fx = lx + 4l + - 3

Reorder the terms:

fx = - 3 + 4l + lx

Solving

fx = - 3 + 4l + lx

Solving for variable 'f'.

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

Divide each side by 'x'.

f = - 3x-1 + 4lx-1 + l

Simplifying

f = - 3x-1 + 4lx-1 + l

Reorder the terms:

f = l + 4lx-1 + - 3x-1
