Question 152854
I hope this is what the problem looks like. If not, reply back to my answer and I'll make the corrections.
<br>We faced with anything with parentheses and absolute value sings, the first thing to do is to try to simplify anything inside them:
{{{3*(-5 + 4p) - (- (-2^2))*p = -5p*(-3^0)-(-1)^3 - abs(-9)}}}
{{{3*(-5 + 4p) - (- highlight((-2^2)))*p = -5p*highlight((-3^0))-(-1)^3 - highlight(abs(-9))}}}
{{{3*(-5 + 4p) - (- (-4))*p = -5p*(-1)-(-1)^3 - 9}}}
{{{3*(-5 + 4p) - highlight(- (-4))*p = -5p*(-1)- highlight((-1)^3) - 9}}}
{{{3*(-5 + 4p) - 4p = -5p*(-1)-(-1) - 9}}}
<br>Now it should be much easier to multiply out everything else:
{{{3*(-5 + 4p) - 4p = -5p*(-1)-(-1) - 9}}}
{{{highlight(3*(-5 + 4p)) - 4*p = highlight(-5p*(-1))highlight(-(-1)) - 9}}}
{{{-15 + 12p - 4p = 5p + 1 - 9}}}
{{{-15 + highlight(12p - 4p) = 5p + highlight(1 - 9)}}}
{{{-15 + 8p = 5p - 8}}}
<br>In order to solve it, we need to put all the variables on one side and all the numbers on the other:
{{{-15 + 8p = 5p - 8}}}
{{{-15 + 8p - 5p = 5p - 5p - 8}}}
{{{-15 + 3p = -8}}}
{{{-15 + 15 + 3p = -8 + 15}}}
{{{3p = 7}}}
{{{p = 7/3}}}
It looks like p = 7/3.
