what is the output for f(x)=5^2+7, f(x) =8-3x

f(x)=5^2+7, f(x) =8-3x

\(f(x)=5^2+7=32\)

                                           [ Equilibrium

\(f(x)=8-3x\)

\(32=8- {\color{red}3} x\)                   [+3x; -32 on both sides

\({\color{red}3}x=8-32=-24\)    [ / 3   on both sides

\(x=-8\)

f(x)=5^2+7, f(x) =8-3x

5^2 + 7 =  8 - 3x

       32 = 8-2x     |-8

       24 = -2x       | : (-2)  

         x = -12
