Question 1151507
Can you write differently or is that meant exactly as shown?


-6 +3 x (5-7x) = -9 -10x
{{{-6 +3 x (5-7x) = -9 -10x}}}


{{{-6+15x-21x^2=-9x-10x}}}

{{{6-15x+21x^2=9x+10x}}}

{{{21x^2-15x-10x-9x+6=0}}}

{{{21x^2-34x+6=0}}}, and you can try to factor this, or use general quadratic formula solution.

If this outlined character is intended as a multiplication symbol and not as variable, {{{-6+3*highlight(x)(5-7x)=-9 -10x}}}, then  {{{x=18/11}}}.
