You can put this solution on YOUR website! -4p-10(2p-3)=22-7(1-2p) --> first calculate the multiplication
-4p-20p+30=22-7+14p
30-22+7=14p+20p+4p --> organize "p" and single numbers but don't forget of change the signal when you exchange the number's side
15=38p --> calculate them
15/38=p --> pass the number that is multiplying dividing to isolate "P"
