Question 155573
-3 = {{{(4000/(p-130))*((130+p)/16000)}}}
Deal with what's on the right side of the equation first
simplify; divide 4000 in to 16000, then mult numerators & denominators
{{{(1/(p-130))*((130+p)/4)}}} = {{{(130+p)/(4(p-130))}}} = {{{(130+p)/(4p-520)}}}
:
Now we can write the equation as:
{{{(130+p)/(4p-520)}}} = -3
;
Multiply both sides by (4p-520)
130+ p = -3(4p-520)
:
130 + p = -12p + 1560
:
p + 12p = 1560 - 130
:
13p = 1430
p = {{{1430/13}}}
p = 110
