What is the solution for this problem 3p-1=5(p-1)-2(7-2p)
2 answers:
______________
3p-1=5(p-1)-2(7-2p)
3p-1=5p-5-14+4p
3p-1=9p-19
6p=18
p=18/6
p=3
____________
3p-1=5(p-1)-2(7-2p)
multiply the first bracket by 5
(5)(p)=5p
(5)(-1)=-5
multiply the second bracket by -2
(-2)(7)=-14
(-2)(-2p)=4p
3p-1=5p-5-14+4p
3p-1=5p+4p-5-14 ( combine like terms)
3p-1=9p-19
move 9p to the other side
sign changes from +9p to -9p
3p-9p-1=9p-9p-19
-6p-1=-19
move -1 to the other side
-6p-1+1=-19+1
-6p=-18
divide both sides by -6 to get p by itself
to get +p
-6p/-6=-18/-6
Answer:
p=3
