Example.

\(\large\color{black}{ \displaystyle 8\cdot x-\sqrt{19}\cdot x+5 =0 }\)
\(\large\color{black}{ \displaystyle (8-\sqrt{19})\cdot x+5 =0 }\)
\(\large\color{black}{ \displaystyle (87-\sqrt{19})\cdot x=-5 }\)
\(\large\color{black}{ \displaystyle x=-5/(8-\sqrt{19}) }\)

Answer 7

im sorry im lost what did u do

Answer 8

did u factor

Answer 9

I subtracted the (√19)•x,
then I factored the first two things out of x,
then subtracted five from both sides,
then divided by 8-(√19), {or by x's coefficient}, on both sides.
