Step-by-step explanation:
x=p+1 (Given)
1/2(5x-30)-1/3(1+7p)=1/4
=>. {5x/2 -(15)} -{1/3+7p/3}= 1/4
=> 5x/3-15-1/3-7p/3=1/4
=> 5(p+1)/3-(15+1/3)-7p/3=1/4
=> 5p+5/3-46/3-7p/3=1/4
=> -{46/3+2p+5)/3}=1/4
=>. -46/3-2p+5/3= 1/4
=>. 2p+5/3 = -46/3-1/4
=> 2p+5= 3(-46/3) -3(1/4)
=> 2p+5 = -46-3/4
=>. 2p= -46-5-3/4
=>. p= 2(-46) -2(5) -2(3/4)
=>. p= -92-10-3/2
=> p= -102-3/2
=> p= -(204-3)/2
=>. p= -201/2
=> p= -100+1/2
