I5p+12I = 7

there will most likely be 2 solutions

if we treat it as 5p+12= +or-7 then it may be easier to see what is happening (if we get an answer of -7 from the equation, it will be changed back to +7 by the absolute value)

so we have 2 equations now

(1)5p+12=7

(2)5p+12=-7

(1)5p=-5 p=-1

(2)5p=-19 p=-3.8

unsure with any of the steps just tell me :)
