Question 281537
I am assuming you know how to distribute and solve for an equation, here is the steps to complete this:

{{{7 (5x+8)=12-(x+4)}}}
{{{35x + 56 = 12 - x - 4}}}
{{{36x = - 48}}}
{{{x = -48/36}}}
{{{x = -4/3}}}

I hope this helps, the distribution process means multiplying 7 to both 5x and 8, do the same thing with the negative on the right side of the equation.
