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