Question

If x=p+1 find the value of p from the equation 1/2(5x-30)-1/3(1+7p)=1/4

Answer 1

Hi ,

x = p +1 ----( 1 )

1/2 (5x -30 ) - 1/3 ( 1+ 7p )= 1/4

[3( 5x - 30 )- 2(1 + 7p ) ]/6= 1/4

15x - 90 -2 - 14p = 6/4

15(p+1 ) - 92 - 14p = 3/2

15p + 15 - 92 - 14p = 3/2

p - 77 = 3/2

p = 3/2 + 77

p = ( 3 + 154 ) /2

p = 157 /2

p = 78.5

I hope this helps you.
