8 7 p − 4 1 = 2 1 p 8 7 p − 4 1 ( 2 = 2 p ( 4 7 p − 2 = 4 p 7 p − 4 p = 2 3 p = 2 p = 3 2
if you mean 8 p 7 − 4 1 = 2 p 1 then multiply by p to give 8 7 − 4 p = 2 1 then multiply by 8 to give 7 − 2 p = 4 subtract 7 − 2 p = − 3 divide by -2 p = 2 3
if you mean ( 8 7 ) p − 4 1 = ( 2 1 ) then multiply by 8 to give 7 p − 2 = 4 p subtract 4p 3 p − 2 = 0 add 2 3 p = 2 then divide by 3 p = 3 2
hope that helps
To solve the equation 8 7 p − 4 1 = 2 1 p , we eliminate fractions by multiplying by 8, rearranging terms, and isolating p. The solution is p = 3 2 .
