2\left(5p+\frac{4p-7}{2}\right)-224p=84\left(\frac{1-8p}{4}+p\right)
Multiply both sides of the equation by 28, the least common multiple of 14,2,4.
10p+2\times \frac{4p-7}{2}-224p=84\left(\frac{1-8p}{4}+p\right)
Use the distributive property to multiply 2 by 5p+\frac{4p-7}{2}.
10p+\frac{2\left(4p-7\right)}{2}-224p=84\left(\frac{1-8p}{4}+p\right)
Express 2\times \frac{4p-7}{2} as a single fraction.
10p+4p-7-224p=84\left(\frac{1-8p}{4}+p\right)
Cancel out 2 and 2.
14p-7-224p=84\left(\frac{1-8p}{4}+p\right)
Combine 10p and 4p to get 14p.
-210p-7=84\left(\frac{1-8p}{4}+p\right)
Combine 14p and -224p to get -210p.
-210p-7=84\times \frac{1-8p}{4}+84p
Use the distributive property to multiply 84 by \frac{1-8p}{4}+p.
-210p-7=21\left(1-8p\right)+84p
Cancel out 4, the greatest common factor in 84 and 4.
-210p-7=21-168p+84p
Use the distributive property to multiply 21 by 1-8p.
-210p-7=21-84p
Combine -168p and 84p to get -84p.
-210p-7+84p=21
Add 84p to both sides.
-126p-7=21
Combine -210p and 84p to get -126p.
-126p=21+7
Add 7 to both sides.
-126p=28
Add 21 and 7 to get 28.
p=\frac{28}{-126}
Divide both sides by -126.
p=-\frac{2}{9}
Reduce the fraction \frac{28}{-126} to lowest terms by extracting and canceling out 14.
