Solution for f(x)=7x-3find(f+g)(3) equation: 


Simplifying
f(x) = 7x + -3find(f + g)(3)

Multiply f * x
fx = 7x + -3find(f + g)(3)

Reorder the terms for easier multiplication:
fx = 7x + -3 * 3dfin(f + g)

Multiply -3 * 3
fx = 7x + -9dfin(f + g)
fx = 7x + (f * -9dfin + g * -9dfin)

Reorder the terms:
fx = 7x + (-9dfgin + -9df2in)
fx = 7x + (-9dfgin + -9df2in)

Reorder the terms:
fx = -9dfgin + -9df2in + 7x

Solving
fx = -9dfgin + -9df2in + 7x

Solving for variable 'f'.

Reorder the terms:
9dfgin + 9df2in + fx + -7x = -9dfgin + -9df2in + 7x + 9dfgin + 9df2in + -7x

Reorder the terms:
9dfgin + 9df2in + fx + -7x = -9dfgin + 9dfgin + -9df2in + 9df2in + 7x + -7x

Combine like terms: -9dfgin + 9dfgin = 0
9dfgin + 9df2in + fx + -7x = 0 + -9df2in + 9df2in + 7x + -7x
9dfgin + 9df2in + fx + -7x = -9df2in + 9df2in + 7x + -7x

Combine like terms: -9df2in + 9df2in = 0
9dfgin + 9df2in + fx + -7x = 0 + 7x + -7x
9dfgin + 9df2in + fx + -7x = 7x + -7x

Combine like terms: 7x + -7x = 0
9dfgin + 9df2in + fx + -7x = 0
