1)p-2/3 +p/4 =1/2 ----(1)
\n" ); document.write( "p+p/4 =1/2+ 2/3 (grouping like terms changing sign while changing side)
\n" ); document.write( "Multiplying through out by 12 (which is the lcm of 2,3 and 4
\n" ); document.write( "12p +3p = 6 + 8
\n" ); document.write( "15p = 14
\n" ); document.write( "p=14/15
\n" ); document.write( "Answer: p = 14/15
\n" ); document.write( "Verification: Putting p=14/15 in (1),LHS simplifies to 1/2 = RHS\r
\n" ); document.write( "\n" ); document.write( "2)4p-8/12 + 3p/12 =6 ----(2)
\n" ); document.write( "Multiplying through out by 12
\n" ); document.write( "4pX12-8+3p =6X12
\n" ); document.write( "48p-8+3p=72
\n" ); document.write( "(48p+3p) = 72+8
\n" ); document.write( "51p = 80
\n" ); document.write( "p= 80/51
\n" ); document.write( "Answer:p= 80/51
\n" ); document.write( "Verification: Putting p=80/51 in (2),
\n" ); document.write( "LHS simplifies to 320/51-2/3+20/51 = 306/51 =6 = RHS\r
\n" ); document.write( "\n" ); document.write( "3)7p-2/3=6 ----(3)
\n" ); document.write( "7p = 6+2/3
\n" ); document.write( "7p =(6X3+2)/3
\n" ); document.write( "7p = 20/3
\n" ); document.write( "Dividing by 7 (that is multiplying by (1/7)
\n" ); document.write( "p= (20/3)X(1/7) = 20/21
\n" ); document.write( "Answer: p = 20/21
\n" ); document.write( "Verification: p = 20/21 in LHS of (1)
\n" ); document.write( "gives 7p-2/3 = 7X(20/21)-2/3 = 20/3-2/3 = (20-2)/3 = 18/3 = 6 =RHS\r
